Zero is Our Hero
Students use construction paper to make a set of folding cards that initially hide a zero and then open to reveal a new number. They put their cards into sequential order and recognize numbers as they count by ten.

Choral Counting I
Using a 100s chart or a number line with a pointer, work with your class to count up to 100 by ones and tens. As a part of daily instruction, prompt your kindergartners to chant count from 1 to 30. Move on to 1 to 50, and then from 1 to...
