Ms. Hansen’s math group at  St. Edward-Epiphany has third and fourth grade students. They are beginning a unit on solving addition and subtraction word problems.

The students and Ms. Hansen first started by doing a word sort of addition and subtraction key words. The students were paired up and each pair were given different addition and subtraction key words. They worked together to sort the words into the correct columns. Then we had a discussion on why they placed certain words into either the addition or subtraction column.

Next Ms. Hansen introduced a problem solving strategy called CUBES.

  • C – Circle the key numbers.
  • U – Underline the question.
  • B – Box math action words.
  • E – Evaluate what steps do I take.
  • S – Solve and check.

 

 

Then Ms. Hansen also modeled how to solve a word problem using this strategy.

We then solved a problem together going through the Cubes strategy.

Then I had them use the CUBES strategy with their partner to solve a word problem.

Finally, they were assigned addition and subtraction word problems to solve on their own using the CUBES strategy.
