To start to grasp this concept, we practiced counting buttons and grouping them by 10s. Very quickly, we started to see that grouping by 10 made counting large numbers much easier. This is something that you could have your child do at home as it is a fun and easy process. Here is what we did:
1. Used cups to help us count the buttons
2. Filled each cup with 10 buttons. Left the single buttons on the table in front of the cups.
3. Drew a picture to show the cups and labelled each cup skip counting by 10
4. Under the picture we wrote how many tens and ones we had and then we wrote the total number.

1. Is it faster for you to count by ones or by tens? Why do you think that?
2. Did you make a mistake counting? How did grouping by 10 help you when you made a mistake?
3. How can you use the cups to help you count?
4. When would you use this in real life?
Tomorrow, we will continue to work on this and then we will do a similar math activity but use blocks and start to form ten rods. Using tens and ones blocks will be a key manipulative through the year and it is important that students understand what they represent and the value they have before we use them.Coming up:
- Photo retakes tomorrow
- Early Dismissal tomorrow
