Subtracting:
This week we have been using part part whole models and tens frames to subtract. We learnt how to identify the missing part by using tens frames. We placed the right amount of counters on the tens frame to represent the whole. Then we took off the counters shown in the known part. we discovered that the number left was the other missing part.
Problem solving
Later on in the week we looked at tricky word problems such as:
- What is the biggest number you can make by throwing 2 hoops onto the cones?
- What is the smallest number you can make by throwing 2 hoops onto the cones?
How to help at home:
- Can you create your own subtraction word problems?
- Practise using items from around the house to subtract with and make all the possible number sentences.
