Calculate the Answer

Bay District Schools


"Calculate the Answer" allows students to practice independently multiplication and/or addition skills. (This activity is appropriate for a learning center/station).


The student understands and explains the effects of addition, subtraction, and multiplication on whole numbers, decimals, and fractions, including mixed numbers, and the effects of division on whole numbers, including the inverse relationship of multiplication and division.

The student selects the appropriate operation to solve specific problems involving addition, subtraction, and multiplication of whole numbers, decimals, and fractions, and division of whole numbers.


-Sets of index cards with basic fact sums or products. (Example: Product Cards: 27, 14, etc. Sum Cards: 8, 11, etc.)


1. Prepare sets of index cards for the basic fact sums or products.
2. Make sure calculators are available at the learning center/station.
3. Review multiplication and/or addition facts during daily math classes.


Post these directions for the students at a learning center or station:

1. Shuffle either the sum or the product cards and place them face down.

2. Turn over a card and read the sum or product.

3. Pressing only single digits, an operation sign, and the equal sign, use the calculator to show the number on the card. (For example: For the product card 27, you would need to type in 3 x 9 and then hit the equal sign (=) to check your answer).
4. If your answer is correct, do another card.

5. If your answer is incorrect, try again. (Think about the numbers you have already entered and the answer you got. Was the answer too high? Too low? How might you need to adjust the addends or factors in order to end up with the correct sum or product?)


Students increase their proficiency with the multiplication and/or addition facts by correctly answering the multiplication and/or addition facts on a teacher made assessment.

Circulate and formatively assess students as they use the technology tools. Provide assistance for students who are experiencing difficulty and monitor accordingly.


As an extension, have the students mix the sets of sum and product cards at the center. Students would then have to choose the correct operation in order to reach the sum or product given on the card.
