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.

Farm Animals: Standard 8.EE.2 Use square root and cube root symbols to represent solutions to equations of the form x2=p and x3 =p, where p is a positive rational number. Evaluate square roots of small perfect squares and cube roots of small perfect cubes. Know that 2 is irrational.
This formative assessment exemplar was created by a team of Utah educators to be used as a resource in the classroom. It was reviewed for appropriateness by a Bias and Sensitivity/Special Education team and by state mathematics leaders. While no assessment is perfect, it is intended to be used as a formative tool that enables teachers to obtain evidence of student learning, identify assets and gaps in that learning, and adjust instruction for the two dimensions that are important for mathematical learning experiences (i.e., Standards for Mathematical Practice, Major Work of the Grade).

This lesson is focused toward 2nd Grade Math - Shapes - using iPad App Keynote. It includes triangles, quadrilaterals, pentagons, hexagons, and cubes. Time frame - 2 hours - can be expanded or reduced, taught and explored over 4 or 5 short lessonsFormat - Planned for face to face - adaptable to virtual environment - Math Talk would need to be face to face or a syncronous lessoniPad App Needed:  Keynote
