How to Use This Pack

Ten lesson plans, one for each lesson of the first 2nd grade unit, facts and strategies within 20, in teaching order, after an overview page that lays the unit out day by day: a pre-check, the ten 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 quizzes 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. Every strategy starts with counters in ten frames before the numbers alone. Lessons 1.4 to 1.7 are for the states that teach them in 2nd grade; skip the ones your class does not learn. The exit tickets and the unit test are separate packs, made for these lessons.

At Home

Teaching at home? Use the warm up and the "Try it together" step as a short lesson, with snacks or small toys in an egg carton cut to ten cups. The "Words to use" are the way to talk about it, and 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 two ten frames and counters on the tables for the whole unit
Ask "which strategy did you use?" as often as "what is the answer?"
Sort the exit tickets into got it, almost and not yet to plan the next day

Common Core Standards Alignment

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

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.
2.OA.B.2 Add and subtract to 20 quickly using strategies done in the head, and by year's end instantly recall every sum of two single-digit numbers.
2.NBT.B.6 Find the sum of two, three or four two-digit numbers using place value and properties of addition.
