Patterns in Counting
Students learn to count in multiples of numbers using concrete objects and a calculator. They also connect number symbols to quantities, and look for patterns in the number symbols.https://education.ti.com/en/activity/detail/patterns-in-counting
Patterns in Percent
Students will use the % key to collect data about percentages of a given number. They will organize the data and look for patterns in percents. (For example, 10% of 20 is twice as much as 5% of 20.)https://education.ti.com/en/activity/detail/patterns-in-percent
Remainder Rules
