I can read, say, and count numbers to 100, jump by tens, and use a number line.
In this mission, you will practice counting forward (up) and backward (down) between 0 and 100. You will use a hundred chart and a number line.
Count forward (up)
Count backward (down)

Count a few small objects one by one, touching each as you say the number. Now point to a number like twenty on your chart and count forward, then backward. Take your time and repeat it once more. When you’re ready, open the tracing pad and write one number you counted. Try another number after that. Say each number as you write it.

Put the numbers from 1 to 10 in order.
Put the numbers from 5 to 14 in order.
