We have recapped on the names and features of 2 and 3D shapes. This shape song is great! We can recognise shapes from pictures and build corresponding models.

There are some extra 2D shapes on here as some of you are ready to be more specific. Here is a cool song for 2d shapes!

Block A3- place value and calculations

4/16/2013

0 Comments

 
Picture
We have focused on subtraction methods using knowledge of number facts and jumps of 10. 


Picture
This shows how you can reorder or reverse a calculation to find a missing number. Remember which are opposites and which can be swopped around to help you work out the answer.

This week's homework was quite tricky as for simple things like place value and rounding we are starting to use Y3 resources. One question that has come up is about rounding- if the number ends in 5 ROUND IT UP! We have talked about this.

Tomorrow we will have an end of unit assessment.

Fractions

We worked out 1/4, 1/2, 3/4 of shapes, they have to be regular to do this. We found out that 2/4 = 1/2.
We used different methods such as sharing and drawing grids to work out fractions of numbers. Some people have good knowledge of their division facts so were able to work out fractions very quickly.

We are having the Block E2 test tomorrow so have a look back over this unit's work :)

How confident are you with numbers to 1000???

3/24/2013

We have noticed that lots of us find it difficult to bridge 3 digit numbers. Use a number line to help you understand what goes either side of the big number- see the photo.

Practise adding and taking away 10 e.g. 283+10, 603-10.

You can also practice counting. We will do more on this over the week and after the holiday.

Division

This week we are focusing on division methods. You can do repeated subtraction, as in this photo or sharing. We used number lines and practical equipment to help us. 

Some people have very good knowledge of their multiplication and division facts which helps them calculate quickly. You should at least know your facts for 2,5,10 times table and corresponding division.

We will also be doing division with remainders using these same methods.

Practise your division using the game below

Division with remainders
We applied the same sharing methods to numbers that don't divide equally. We also used number lines to found up or down in jumps then saw what was left- the remainder. See photo.

A couple of tricks we discovered were that when you times by 10 you add a zero to the answer e.g 7x10= 70 so as division is the opposite, when you divide by 10 you knock off a zero e.g 70 divided by 10 = 7.

Instructions

We learned that 1/4 turn= 90 degrees, 1/2 turn is 180 and 3/4 turn is 270. We programmed the roamer with instructions to turn clockwise or anti clockwise. We set challenges like making it go to someone, turn then come back. We had to estimate how many lengths to tell the Roamer to travel.

We looked at turning a shape 1/4, 1/2 or 3/4 clockwise or antilock wise turns.

We are learning the time. You should know quarter past, quarter to and half past. How can you write them as digital e.g half past 7= 7:30.
Play these games to help you and also use your knowledge to solve time problems. Practise telling the time at home as much as you some of you are finding this difficult.

If the world were a village of 100 people- data handling

2/18/2013

To make data handling more interesting we are using the context of this famous social studies book.
Today we watched the clips and thought about how we could present this information for more easy comparison. We make bar charts or pictograms of the Village Nationalities using our dividing by 10 and fraction skills as well as working out scales. We will try doing the same for the languages spoken.
We will go on to interpret the data and draw conclusions as we will collect the same data on our the people in our Numeracy class to see if we are representative of the whole world. 

Click on the above picture for the video. Here are a couple more links too:

Block C- measure and data handling

2/6/2013

0 Comments

 
Picture
This week we used the Guinness Book of Records to find measurements and discuss the appropriate units used. We worked out a scale to make a height chart on which we marked the shortest people in the world, the tallest and some of us as well.

We had a challenge to find which is the heaviest object in the classroom that would fit in a scale bucket. We had to work out how to collect and organise the measurements.

Play these games to practice your basic measuring and data handling skills. We will continue this unit after the holiday.

Knowing our numbers

We worked out all the pairs of numbers that add to 20 e.g. 12+8, you should know these as number facts. We worked out the multiples of 10 that add together to make 100 e.g. 30+5- you should also know these as number facts.

We worked out missing numbers from sentences by reordering them e.g.
__ + 14= 21
can be written as 21-14=_____ Use a number line to count down in jumps.


We worked out how to identify numbers that are in the 2s, 5s and 10 x table- can you remember the rules? 

Picture
We are using these skills to solve money problems. We have looked at the coins again to remind yourself about the British coins. 
Play this game to practice adding and subtracting money.
