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.
