How to Use This Pack

Nine lesson plans, one for each lesson of a 3rd grade unit on adding and subtracting within 1,000, in teaching order, after an overview page that lays the unit out day by day: a pre-check, the nine lessons, a review and the unit test. Each plan fits on one page. It gives the goal, what to get ready, the words to use, the lesson in five steps with the words to say, questions to ask, common mistakes and what to do about them, and the Animal Math worksheets, makers, tools and quiz for the lesson.

In the Classroom

Print the unit, or just the day's page, and teach from it. Each lesson takes about 45 minutes: a 5 minute warm up, 10 minutes of teaching, 10 minutes together, 15 minutes of practice and an exit ticket at the end. The exit tickets and the unit test are separate packs, made for these lessons. Lessons 6.8 and 6.9 (four-digit numbers, and equal or not equal) are taught in 3rd grade in some states, such as Georgia; skip them if yours teaches them in another grade.

At Home

Teaching at home? Use the warm up and the "Try it together" step as a short lesson, and the "Words to use" as the way to talk about it. Paper squares, strips and dots work as well as base-ten blocks. The mistakes to watch for are the ones most children make.

Tips for Success

Read the "Watch for" box before the lesson: it is what to listen for while students work
Keep base-ten blocks on the tables for the first lessons of the unit
Have students check every subtraction by adding the answer back
Sort the exit tickets into got it, almost and not yet to plan the next day
Use the help and challenge ideas for small groups during practice

Common Core Standards Alignment

This pack supports the following Common Core State Standards for Mathematics:

3.OA.D.8 Solve two-step story problems with +, −, × and ÷, using a letter for the missing amount, and check answers by estimating or rounding.
