In this lesson, students will use mathematical reasoning and the four operations to solve math riddle problems. They will work with a partner to read and discuss the riddle together to figure out the answer and then place in a class book.

This short video and interactive assessment activity is designed to teach fourth graders about finding the adjusted rate - word problems.

This video shows two different student-generated strategies for solving fair share problems leading to a fraction less than 1. This standard relates to Common Core standard 5.NF.3, and North Carolina standard NC.5.NF.3.

The end of this video helps teachers see how standard NF.3 can be introduced prior to NF.1 (addition/subraction of fractions with unlike denominators).

This is a fun interactive game that allows students to practice their basic math fact fluency.

G3M1: Properties of Multiplication and Division and Solving Problems with Units of 2–5 and 10. Contains 21 Lessons.

G3M3: Multiplication and Division with Units of 0, 1, 6–9, and Multiples of 10. Contains 21 Lessons.

The first of these word problems is a multiplication problem involving equal-sized groups. The next two reflect the two related division problems, namely, "How many groups?" and "How many in each group?"

The purpose of this task is to show three problems that are set in the same kind of context, but the first is a straightforward multiplication problem while the other two are the corresponding "How many groups?" and "How many in each group?" division problems.
