Making Subtraction FUN with Smarties!
We introduced subtraction to our little ones this week and what better way to do it than with some sugar!
This Smarties Subtraction lesson worked a treat! 😛 (pun intended!)
Each student was given a box of Smarties and was asked to count how many there were in their box.
Then they were asked to eat a few and count how many were left.
Children then recorded the corresponding subtraction number sentence.
Each child continued eating their smarties and recorded the number sentences until there were none left.
Following this lesson, we discussed what subtraction is and what happens to numbers when we subtract;
ie: the number gets smaller.
We practised creating subtraction number sentences as a class and discussed what each part of the number sentence represents.
This was a great opportunity to share the various subtraction strategies that can be used to help solve subtraction problems. Materials such as hundreds charts and a number lines were mentioned as things we can use to assist in ‘Counting Back’ as well as the ‘Jump Method’.
We will revisit these strategies over the next few lessons and go into them in more detail throughout the term. As I introduce and model each new strategy to my class, I always make sure they have a visual in the classroom so that if can be referred to when the children are working independently. I ensure I introduce and display each strategy one at a time to ensure they are not overwhelmed.
