Discussion Questions
 Before VideoHow do we count from 1 to 10?ANSWER
One, two, three, four, five, six, seven, eight, nine, ten.
4, 5, 6, 7, 8.
9.
I can count to find how many. When I count a ball, I can take it out of the basket so I know how many I have left to count.
First count 1, 2, 3, 4, 5 to go in one basket. Then count the leftover balls to go in the other basket: 1, 2, 3, 4, 5.
 After VideoSay all the numbers after 10 up to 20.ANSWER
Eleven, twelve, thirteen, fourteen, fifteen, sixteen, seventeen, eighteen, nineteen, twenty.
We say twenty and then each of the numbers between 1 and 9. After twentynine is 30.
Ten, twenty, thirty, forty, fifty, sixty, seventy, eighty, ninety, one hundred.
45 has a 5, so the next number will have a 6. The next number is 46.
79 is the last "seventy" number. So, the next number starts with 8: 80.
