First grade students need to be able to count tens and ones. First graders should know that in a two-digit number, the first digit is the number of tens and the second digit is the number of ones. Using their awesome knowledge of tens and ones, students should be able to compare two numbers with a greater than (<), less than (>) or equal (=) sign.

For Students!
We use a chart like the one above to learn place value at school. You can do this at home, too! Here's how:
1. Collect three plastic sandwich baggies.
2. Ask a family member for some straws and some rubber bands. You can also use hair bands!
3. Begin counting! You can count the days until vacation, the days until your birthday... anything really! Make sure to label your baggies "hundreds", "tens", and "ones".
