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!
