missing-factors-and-multiplication-word-problems-lesson-for-3rd-or-4th-grade-math

In this 3rd or 4th grade multiplication lesson, we first find factors of 16 and 48 (to be more exact, we find missing numbers in the expressions ___x___ = 16 and ___x___ = 48.

Then, we solve two multiplication-related word problems. In the first one, we know the price of tomato plants ($5) and of pepper plants ($3). Mathy (my mascot) buys 4 tomato plants and 6 pepper plants. What is his total cost?

The second problem is solved by guess and check. It asks how many tomato and how many pepper plants were bought if the total was $30.
