Unit 04 Resources

In Grade 3, students solved one-step and two-step problems involving division within 100 using various strategies and were also able to represent those division situations using strip diagrams and equations. Students also used rounding to the nearest 10 or 100 and compatible numbers to estimate solutions in addition and subtraction situations. In Grade 4, Units 02 – 03, students used rounding to the nearest 10, 100, or 1,000 as well as compatible numbers to make reasonable estimates in addition and subtraction problems. They also used various models and representations to solve multiplication problems.

 

In Grade 4, Students represent quotients of up to four-digit whole number dividends by one-digit whole number divisors using arrays, area models, and equations. As students experience various division strategies and algorithms, including the standard algorithm, they begin to develop fluency of the operation of division. Students are expected to solve fluently one- and two-step problems involving division, including the interpretation of remainders. This unit also includes representing division problem situations using strip diagrams and equations with a letter standing for the unknown quantity. Students continue to use estimation, rounding, and compatible numbers, to find estimates and justify reasonableness for solutions to problems involving division.
