How the lesson starts: Read, Write, and Represent Numbers to 120

1. Zip builds numbers

   Hello! Meet Zip the robot. Beep boop! Zip builds numbers out of blocks. A long rod is 10. A little cube is 1. Let's help Zip read the blocks!

2. Read the blocks

   Zip builds this. Count the rods by tens. 10, 20, 30, 40, 50, 60. Now count on with the cubes. 61, 62, 63, 64. It's 64!

3. Which number is this?

   Zip builds 2 rods and 5 cubes. Count rods by tens. 10, 20. Count on cubes. 21, 22, 23, 24, 25. It's 25! Watch out! Not 52. The tens digit goes first.
