Hi we are Group Lollie-Pops. Over the past week we have been learning how to skip count in tidy numbers on a number line.
It was really tricky at first, but it is slowly getting easier.
We love number lines!
We use number lines and tidy numbers when we are adding and subtracting.
This is how you do it....
23 + ___ = 40
First you start from 23 ... then you jump to the closest tidy number (tidy numbers end in a 0) which is 30. So I keep 7 in my head. Then I jump to 40 (which is 10 more). So I add 7 and 10 together and get the answer ... 23 + 17 = 40
Wow Room 15. I love the way you are using number lines to solve these problems. Soon you will be able to do it in your head!
