Unit 05 Resources

Unit 05 - All Operations

In previous units, students have used addition or subtraction with whole numbers and decimals to tenths and hundredths to solve problems. Students also examined multiplication and division separately using strip diagrams and equations to represent problem situations. Students solved one- or two-step problems involving multiplication and division, which included interpreting remainders.

In Grade 3, students represented real-world relationships using number pairs in a table and verbal descriptions.

During this unit, students will apply previously learned concepts to solve one-, two-, or multi-step problems involving addition and subtraction of whole numbers and decimals to the hundredths place, multiplication of whole numbers up to two-digit factors and up to four-digit factors by one-digit factors, and division of whole numbers up to four-digit dividends by one-digit divisors with remainders in appropriate contexts. Students examine financial literacy situations that involve calculating a profit and learn to distinguish between fixed and variable expenses.
