This week in Maths we have been exploring symmetry, looking at how shapes are reflected in lines of symmetry. We extended this to reflect shapes and images through 2 lines of symmetry and used this process to create our own colourful symmetrical patterns. We also looked a selection of images and through using a mirror identified where lines of symmetry would fall across shapes to make perfect reflections on either side.
In our first week back of term 2 we took some simple incomplete addition number sentences and attempted to explain their meaning by inverting the calculation, creating 2 addition facts and 2 subtraction facts from the first number sentence. e.g. 12 + ? = 27 can be rearranged to form: ? + 12 = 27 and 27 - ? = 12, 27 - 12 = ?.
We then looked at which of these facts could be used easily to help us solve and complete the number sentence.
We also looked at finding the difference between 2 numbers and worked hard to explain the methods we were using to solve number sentences. Alongside our Big Maths challenge, the class also managed to finish 2 loop card games reciting the 2x and 10x table facts both in under 60 seconds! Next week we will see how much quicker we can complete them. A good start back to the term, well done Maths group.
Using some great Maths vocabulary this week, our Maths class were exploring balancing scales and weight. We had a selection of objects in the classroom and had to discuss in groups which objects we thought were eavier than, lighter than and the same weight as something else. We then got to investigate weight using the balancing scales to find out and record our results. We also explored word problems involving measure and got to create some 1 and 2 step problems for a friend. Many new personal best scores for our Big Maths challenge this week!
This week we have started looking at our unit on data handling. We've made and conducted a survey as well as creating a block graph to represent this information. The most fun we had was getting 'hands on' with measuring height of children (and teachers) in the class!
This week in Maths we have been looking at 2D and 3D shapes. We have carefully described their properties using Maths vocabulary such as edges, vertices and faces and then thought about how we could sort them using a Venn Diagram.
This week we took our known number bonds to 10, number bonds to 20 and simple addition facts such as 6+3=9 to apply them to larger calculations. We used them to help complete number sentences for multiples of 10 (60+30=90) and multiples of 100 (600+300=900). We all did very well. To challenge us further we then thought about number sentences where we added multiples of 10 and multiples of 100. Most of us kept a high level of accuracy when adding the multiple of 10 crossed over into a new hundreds value. We have also been looking at doubling and halving this week, increasing our speed and accuracy in recalling facts for numbers to 20 and numbers to 100. Next week everyone is looking to beat their Big Maths challenge score from this week!
This week in Maths we have been comparing numbers using < and > as well as exploring different number sequences, finding out the rule and then using it to extend or complete the number sequence. We all had to think hard about how to complete some of the number sequences, but there were a few students who cracked the rule in record timing! We also began our Maths challenge which will focus on our rapid recall of simple arithmetic facts we should know in Year 2.
This week in Maths we have been looking at place value. We have been working with 2, 3 and 4 digit numbers. We used arrow cards to build them and then partitioned them again back into hundreds, tens and units. We found it challenging when we looked at writing 4-digit numbers in words but no-one gave up! This week we also started to look at large numbers and explored how we could group them, being careful to record how many equal groups could be made and if there were any remainders.
Here is a website with arrow cards if you want to try writing more 3-digit and 4-digit numbers at home!
We have been learning how to tell the time in 5 minute intervals. There are many ways to read and write it! Luke's clock here says 'ten to 1' or we could write it as 1:50. AM is morning and PM is afternoon.
We have also been looking at calculation strategies to work out money problems:
Ellen has a £5 note. She spends £3.99. Draw the smallest number of coins she would get her change in.
This is a 2 step problem. We counted from 3.99 up to 5 using a number line to calculate the change, then worked out which coins we could use.
The answer is £1.01 so we would get a £1 coin and a 1p coin change.
Practise questions like this at home.
This week we are focusing on Weight, length and capacity. You should know what equipment and which units to measure with. E.g You would measure the length of a pencil with a ruler in cms.
There are lots of bite size games to play to revise this.
We used our knowledge of measure to solve problems and challenges. We even incorporated our calculation skills.
Make sure you know what these words are!
and what operation you would do if you saw them in a word problem.
