Module 1- Sums and Differences to 20

Module 1 sets the foundation for students to master sums and differences to 20. Students subsequently apply these skills to fluently add one-digit to two-digit numbers at least through 100 using place value understanding, properties of operations, and the relationship between addition and subtraction

Home Activities:

• Roll single digit numbers and add them together.

• Roll 2-digit or 3-digit numbers and add them together.

• Use small items (counters, beans, small toys) to represent number sentences. Use index cards to make +, -, <, >, and = symbols. Show a number sentence with a missing element: 7 + ___ = 12. Have your student find the missing addend.

• Make a train with Legos or colored blocks. Write a number sentence for the different colors in the train.
