Grade: 2nd Grade

Content: Addition

N.FL.02.10 Add fluently two numbers through 99, using strategies including formal
algorithms; subtract fluently two numbers through 99.*

Objectives:

Students will:

      Be able to add ones and tens.
      Be able to build, draw and explain addition problems using numbers through 99.
      Understand standard configuration and how to build and solve questions using
       base ten blocks on placemats.
      Understand what the terms addend, combine, sum, plus, ones place and tens place
       mean.

Time: 20 minutes

Literature Connections:

Animals on Board

By: Stuart J. Murphy and Illustrated by: R.W. Alley

The Hershey’s Kisses Addition Book

By: Jerry Pallotta and Illustrated by: Rob Bolster

Flesch-Kincaid grade level:

With complete directions: 2.8

With limited directions: 2.4

* I would read the complete directions out-loud to students before and during the test.

Lesson Idea #1:

      Read Animals on Board to the class.
      Bring animal counters or pictures of animals.
      Have students count and create problems on the placemats using the animal cut-
       outs.

Lesson Idea #2:
      Give students questions to build, draw and explain on their placemats using base-
       ten blocks.
      Provide plenty of practice with these before assessment.

* Give students problems that do not include re-grouping, such as 35+53, 22+16, and
67+31. Introduce regrouping and what the compose- ten column means, but focus first on
combining the addends into the sum.
