This lesson plan is designed to provide students with the opportunity to participate in engaging activities to review previously learned strategies for adding 3-digit numbers within 1,000, as well as practice in explaining their thinking as they solve addition problems.  

This lesson is to teach the problem-solving strategy using the CUBES acronym. The students will use digital photos to create real-life story problems of their own and practice using the CUBES strategy to solve the problems they create as well as those of their peers.

This class activity is designed to introduce young learners to the concept of tree diagrams. This class activity requires learners to organize data about the individual student's physical characteristics(gender, hair and eye color) utilizing connecting cubes. The activity includes a follow up activity, questions, tips on getting started, a teacher resource page, and a printable version of the problem.

This activity provides an opportunity for students to work on spatial visualization and number sense together.
