In this unit, students will study basic computation skills of whole numbers and decimals and build on their number sense abilities.

Topics studied include:
  • Addition and subtraction
  • Multiplication
  • Place value
  • Statistics (mean, median, mode, range)
  • Probability

One of the most important skills students will need for fifth grade math is automatic recall of addition, subtraction, multiplication, and division facts. I strongly encourage all students to practice math facts at home for at least 5 minutes each night. Our class will be charting progress as we take Facts Master practice tests each week, with the goal of correctly answering all 300 problems in under 10 minutes.
