How to Use This Pack

Twelve lesson plans, one for each lesson of a unit on addition strategies to 20, in teaching order, after an overview page that lays the unit out day by day: a pre-check, the twelve 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. Each strategy leans on the one before, so teach the lessons in order.

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. 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 a double ten frame and counters on every desk all unit
  • Sort the exit tickets into got it, almost and not yet to plan the next day
  • Ask "How did you find it?" as often as "What is the sum?"

Common Core Standards Alignment

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

  • K.OA.A.3 Break a number up to 10 into two parts several ways, recording each as a picture or equation (7 = 3 + 4).
  • K.OA.A.4 For a number from 1 to 9, find the partner that adds with it to 10, and show it in a picture or number sentence.
  • 1.OA.A.2 Solve story problems where three numbers are added together for a total of 20 or less.
  • 1.OA.B.3 Use the order and grouping rules of addition as shortcuts, for example knowing 5 + 9 gives the same answer as 9 + 5.
  • 1.OA.B.4 Treat subtraction as finding a missing addend: to solve 12 - 9, ask what added to 9 makes 12.
  • 1.OA.C.5 Connect counting with adding and subtracting, such as adding 4 by counting on four more.
  • 1.OA.C.6 Add and subtract to 20, working fluently within 10, with strategies like counting on, making ten, fact families and doubles plus one.
  • 1.OA.D.7 Know the equal sign means both sides have the same value, and decide whether addition and subtraction equations hold true.
  • 1.OA.D.8 Solve for the missing number in adding or subtracting equations like 9 + ? = 15 or ? - 4 = 6.

Each one ends with the Animal Math worksheets, worksheet makers, tools and quiz for that lesson. Lessons: count on from the bigger number, turn-around facts, adding zero and true or false, doubles and near doubles, make a ten to add, number bonds to 20, adding three numbers, ways to make 20, addition facts to 20, adding the same number again, and puzzles and games.
