---|---|
Math - Linear Counting | |
Level | Primary |
Age | 4.5 - 5 |
Prerequisites | Hundred Chain |
Materials | Thousand Chain 10 hundred squares 1 thousand cube labels pointer for counting long mat (30' long) |
This activity teaches the child skip counting which is preparation for multiplication. It also indirectly prepares the child to understand cubing numbers.
Presentation
- Show the child how to carry the chain by looping a segment between the hundreds over each finger.
- Lay out the chain on a long mat as shown. Bring the thousand cube, the 10 hundred squares, the labels, and the counter.
- Have one person hold one end of the chain in place while the other person holds the opposite end and stretches the chain down the length of the mat.
- Fold the bead bars as shown to form squares of 100.
- Set the hundred squares on top to show that they are the same.
- Stack the hundred squares next to the thousand cube to show that they are the same.
- Stretch the chain back out again. Sort the labels into columns (1-10 together, 20-100 together, 110-200 together, etc.).
- Count and place labels as you go.
- Move the mat with the labels with you as you work.
- 100, 200, 300, etc. get red labels. The 1000 label at the end is green. The colors correspond to the ones used on the decimal cards.
- Walk the length of the completed chain and read the numbers on the labels.
