Teaching notes for parents and teachers
How to teach it
Model a fact with tens rods and name the unit in the product. Explain why twelve tens is 120.
Example to work through together
Use the model below as you explain the example. Have your student point to the quantities as you discuss them.
Four boxes. Three tens in every box.
4 × 3 tens = 12 tens
12 tens = 120 counters
Each small section represents one counter. Each complete rod represents ten counters.
Ask your student
Are we counting ones or tens in this step?
If your student needs help
If the student adds a zero without understanding why, have them count the tens represented in the model.
Make a practice set
Select the worksheet, answer key, or both. When both are selected, the answer key prints after the questions. Keep it separate if you want your student to work independently.
After your student finishes
Ask how many tens the child found before converting the total to counters. Use a sketch or a second multiplication fact to check the answer.
