This lesson was a exploration lesson where students continued to build their understanding and application of multiplication and division to solve a word problem involving equal groups, arrays, drawings and equations to represent their thinking. The students were challenged to find multiple solution methods and to persevere throughout the task. The students were able to pick an appropriate math tool(s) to assist them with the task. The students were asked to explain and justify their thinking throughout the lesson with their teacher, with a partner, and through a whole group share out.

This lesson primarily focuses on 4.NBT.B.4 - fluently adding and subtracting multi-digit numbers using the standard algorithm. The lesson connects to and builds on students' understanding of place value and the base-ten number system ( 4.NBT.A.1). Students use a step-by-step process to add and subtract multi-digit numbers, as modeled by the teacher. Students then work through word problems that require use of the standard algorithm, first with partners and then independently.
