These two math center activities are aligned with Everyday Math's Decade Count - Lesson 7-13. Everyday Math encourages teachers to do a technology extension using the calculator.
One worksheet in this bundle is a sheet for the activity. It requires students to write the numbers, reflect on what buttons they were pressing on the calculator, breaking the number down into tens and ones and then comparing the two numbers.
Second activity is a roll and write game where students play with one other friend. Students roll the dice, think about the tens and ones and then they do a 'data' sheet where they will determine the winner!
Have your math centers prepped! No sweat, just print copies and you're good to go ;) Enjoy in Kindergarten!
