This resource is a great way for students to build their flexibility with numbers while also engaging in critical thinking. Students will build these math skills through elimination computation. Each problem gives the sum, as well as a set of multiple numbers, and students work to figure which numbers can be added to create that sum.
The questions get progressively more difficult as the sums get larger, and include both 2 addends and 3 addends.
This makes a great math center, or an early finisher activity that keeps students engaged in critical math thinking.
