Draw THREE models for this problem - equal groups, number line, and array. *Reminder: Story problem is the same as a word problem. Typically, the story problem is 2-3 sentences that ends with a question. Model is a drawing that encompasses the mathematics in the problem. 2.) For each problem, describe TWO different ways to solve the problem mentally and show your work through a series of equations. Identify any property that you used in your work. (Look over notes and recordings for help/ideas.) a.) 51 x 4 b.) 5 x 953.) Show the product of 83 x 374 using each of the following methods: a.) Area model b.) Partial products C.) Lattice method
