Students will enjoy reading about some amazing Central and South American monkeys while they solve word problems. These word problems help students apply 3rd grade addition, subtraction, multiplication, and rounding skills. It also provides an opportunity for integrated reading practice. It can also be used as a formative test later in the year, as students need to read for information, determine what operation to use, and apply a math strategy effectively. Finally, it could be used at the start of the year in 4th grade.
