No school - Wednesday 21st May
Week beginning: 21st April
The challenge was to change a number which passed through 2 different function machines before it came out the other end!
We also continued with finding halves and quarters of shapes. We then moved on to using objects such as skittles and m&m's. We split them in half, quarters and thirds! We related this to the division symbol. When we find quarters, we divide by 4, when we find thirds, we divide by 3. We noticed that not all our sweets could be divided equally with certain amounts!
Week beginning: 14th April
Willy Wonka's new sweet shop now OPEN!
We also looked at fractions such as 1/2, 1/4 and 3/4 and folded shapes to help us to notice patterns! Next week we will look at sorting objects such as delicious sweets in to halves, quarters and 3 quarters!
Week beginning: 7th April
Writing numbers in words and figures
Odd and even numbers
Missing number sequences
Doubling and halving word problems
We then moved on to completing missing number calculations. We found some of these a little tricky! Particularly when the number sentence was written backwards! E.g. 36 = 24 + ? So we decided to write it in a way which we would find easier to work out: 24 + ? = 36 remembering that addition and multiplication can be done in any order! We used the method of counting on to find the missing number! We also tried some multiplication number sentences which the children were fantastic at!
We ended the week by using the RUCSAC method to solve word problems involving doubling and halving. We used objects to help us work out the answer and remembered that when we double we are multiplying by 2 and when we half we are dividing by 2. The challenge questions were the 2 step problems! We had to write 2 calculations to find the answer here, eg. Katie has 12 sweets. She shares them between herself and her friend. She then gives her friend another 2. How many does Katie have left?
This week we will be continuing to solve 2 step word problems as Willy Wonka's sweet shop opens up in the classroom! The children are very excited to be given the job as the shop keepers as I have told Willy Wonka what amazing mathematicians they are on the cash machines! :)
Week beginning: 17th March
Solving word problems
1. Read the word problem
2. Underline the important numbers and words
3. Write the calculation (is it an add/subtract/times/divide?)
4. Solve the calculation.
5. Write the answer next to the question.
6. Check your work!
Please continue to practise using and applying the mathematical language associated with each maths symbol, for example:
+ add, plus, total, altogether, more than, count on
- subtract, minus, take away, less than, count back
x times, multiply, groups of, multiplied by
divide, share between, equal amounts
Week beginning: 10th March
Telling the time
We then moved on to telling the time! We begun by reminding ourselves about all the important language we use such as seconds, minutes, hours, clock face, clock hand, clockwise, anti-clockwise. We drew a huge clock on the carpet using chalks and talked about a whole, a half and a quarter making links to our work using clocks and turns. We drew the hands on clocks for quarter past and quarter to times and had to really concentrate on drawings the correct lengths of the hands! This was tricky! Our last focus was moving on to solving word problems such as:
Katie went to the shops at half past 6. She was there for half an hour. What time did Katie return?
I have told the children that the more they can practise at home, using a watch or a wall clock, the easier telling the time will become! Word problems involving time are also much easier to solve when they are in real life contexts. Keep practising, children!
Week beginning: 24th February
We found all the objects in the classroom which measured less than 10cm and more than 10cm. We then sorted them and measured them accurately using a ruler. The tricky part of this lesson was then reading the scale on a ruler using cm's and mm's. We had to look really carefully! We then practised drawing lines to the exact measurement and measured some more objects!
I have been so pleased at how well the children have been performing during our mental maths quizzes on Friday mornings. As they have got used to the style of questions, using and interpreting the mathematical language, they have been scoring more points each week!
As there is no homework or maths lessons this week due to Book Week, please can you continue to practise mental maths questions with your child at home. The ones they have found particularly hard are questions such as, find the difference between 14 and 20 and write 2 numbers which come in between 13 and 20.
Week beginning: 17th February 2014
Sharing objects equally
First we highlighted the important numbers and words. We learnt that the biggest number is the amount of objects we need to start off with. The second number told us how many groups we needed to share the total number between. We counted how many objects were in each group once we had shared them equally, and this was the answer! We then wrote the division calculation! WOW!
*Remember: only EVEN numbers can be split up and divided equally*
After this, we then moved on to looking at data handling. We collected information about our favourite explorers using the tallying system. We decided to use a class list to check we had asked everyone! This method worked much better and our results were then more accurate. We then thought about how we could present our results more clearly so we made a bar graph. I was so impressed at how well the children drew their own axis to create their graphs. After this, they answered questions using the information in the graph and even came up with their own questions for their partner to answer! The tricky style of question we found was: How many more....? We realised this was the same as the 'finding the difference' questions and we just needed to count on from the smaller number to the larger number. Great work children! :)
Week beginning: 10th February 2014
Finding the difference
We then looked at money and went for a spot of shopping! We used coins to help us find the difference by working out the change when we paid with a 50p coin or a 1 pound coin. This was a little harder as we had to work out whether it was easier to take away from the larger number or count on from the smaller number and which would be quickest! Here is a fun, interactive game we have been playing online:
We have also been continuing to practise our 2, 5 and 10 times tables by playing the loop the loop card game. We have been using a range of mathematical language which means times such as groups of, lots of, multiplied by and so far the 5 times table is proving the trickiest!
Week beginning: 20th January 2014
Week beginning: 13th January 2014
Adding and subtracting 2 digit numbers by partitioning
45 + 23 = ?
40 + 20 = 60
5 + 3 = 8
60 + 8 = 68!
The subtraction process was slightly more challenging so we drew number lines and Francessca the frog helped us to partition the number we were taking away so we could count back in 10s then 1s to get to the answer.
Week beginning: 6th January 2014
Reading and writing numbers to 1000 in words and figures
Partitioning 3 digit numbers into H T U
This week we begun by reading and writing numbers in words and figures up to 1000! The children were amazing at this! We have been warming our maths brains up each morning by looking at rounding numbers to the nearest 10. Here is a fun game you can play at home to help you:www.ictgames.com/helipad%20hops7.html
We then went on to look at partitioning 3 digit numbers into Mr. Hundred, Mrs. Ten and Baby Unit. The children had great fun being the different number characters and arranging themselves in the correct order, recognising what each digit stands for and making the numbers 100 more, 10 more or 1 more. We then read a very entertaining story called, 'Zero the hero' which made us realise just how important the number 0 is and how we felt sorry for him always being squashed by bigger numbers!
We then looked at partitioning numbers in different ways using dienes apparatus and shall revisit this next week!
eg. 56 = 50 + 6
40 + 10 + 6
30 + 30 + 3 + 3
10 + 10 + 10 + 10 + 10 + 5 + 1
Week beginning: 4th November 2013
* Remember 1000ml = 1 litre *
We then looked at the last form of measure which is time. We talked about the importance of time and what would happen in the world if there were no clocks! The children had great fun carrying out a selection of activities in 1 minute. They estimated how many times they could write their name in 1 minute, they could build a tower of cubes in 1 minute and how many push ups could they do in 1 minute. They then timed each other using stop clocks, sand timers and the second hand on the classroom clock and I was amazed at how close their estimates were!
* Remember 60 seconds = 1 minute
60 minutes = in 1 hour *
Next week we will move on to reading the hands on the clock and solving word problems involving time!
Week beginning: 28th October 2013
The children used rulers accurately to measure their hand spans and foot lengths and a piece of string to measure their partners head sizes! We measured our heights and found the tallest and the shortest children in our class.
We then talked about the importance of measuring weight and where we have seen things being measured in everyday life. The children had a go at estimating the weights of different objects then weighing them using balance scales. Next week we will begin to look at other forms of measure such as capacity and time.
Week beginning: 7th October 2013
Grouping in 2s, 5s and 10s and solving problems
Victoria bought an ice cream for 80p and a toy car for 20p. How much does she spend altogether?
The number sentence would be: 80p + 20p = 100p/1 pound.
The challenge of the week was working out the change for different amounts if we didn't have the exact money to pay with!
Here is a great interactive website we used....
Week beginning: 23rd September 2013
Shapes all around us!
Week beginning: 16th September 2013
Number facts to 10
Doubling and halving
We then moved on to doubling numbers to 20, recalling these number facts through songs, games and activities involving finger painting! The children recorded all the different double numbers in the form of a number equation, eg. 6 + 6 = 12. They then worked out the inverse to show what happens when you half the number, eg. 12 - 6 = 6. They recognised that if you double a number then half the answer, you will return to the original number again, eg. double 7 is 14 so half of 14 is 7.
Here are some enjoyable websites for you to continue exploring at home:

Week beginning: 9th September 2013
46 = 4 tens and 6 units which is 40 + 6.
We also had a go at using arrow cards so we could see how Mr 0 gets squashed every time a bigger units number comes along! We have played lots of fun games such as place value bingo and 'guess my number' where each child has a different number card and says for example, 'I have 4 tens and 3 units...what am I?'
Here are some great interactive websites we have been using in class to help us with our understanding:
We have also been ordering numbers on a number line from 0 - 100. We learnt the importance of looking at the tens number to help us order the numbers from smallest to largest. If there are two numbers which have the same tens number, then we must look at the units number! We used the symbols < and > to show which number is bigger and which number is smaller. Here is another great game you can play at home:
Week beginning: 2nd September 2013
(Sung to the tune of row, row, row your boat)
9 and 1 are number bonds,
8 and 2 are friends,
7 and 3,
6 and 4,
5 and 5 are twins!
(whisper) Don't forget 10 and 0...0 and 10!
We ended the week by revising odd and even numbers! We played some fun games and met Mr Odd and Mrs Even who helped us to sort and recognise numbers.
1, 3, 7, 9...remember odd numbers all the time!
0, 2, 4, 6, 8...even numbers are so great!
By the end of the lesson the children were able to tell me whether large numbers such as 7653 were odd or even by remembering to always look at the units number! Great work!
Next week we will be looking at place value and partitioning numbers. :)
