About Grade 3 Math

Grade 3 math (3rd grade, ages 8–9) is 40 lessons in 5 units: Numbers and Place Value (lessons 1–8), Operations (lessons 9–16), Fractions and Measurement (lessons 17–24), Geometry and Data (lessons 25–32), and finally Projects & Problem Solving (lessons 33–40), project work that brings the year together. Along the way, children learn to explain division as equal sharing of a quantity among a given number of groups, convert centimeters to meters and meters to centimeters using the relationship 1 m = 100 cm and record data using tally marks.

Start here: Lesson 1: Read and Write Numbers to 10,000 is free to open and print. Every other lesson has a free preview of its mini lesson and vocabulary.

Paper first: each lesson is printed before you call your child. You read it once and talk it through, your child does the exercises on paper, and you correct together with the Parent checklist β€” about 45 minutes at the table. The next day, a 10-minute screen review of the same lesson.
