Learning Objectives

Students will be able to add 10 and 1 fluently to any two digit number.

Lesson

Introduction (7 minutes)

  • Have students gather on the rug. Write the equation 10 + 1 on the board close to the hundreds chart. Have a volunteer show how to solve that equation using the hundreds chart.
  • Now write 10 + 10 on the board. Have another volunteer show what solving that equation looks like on the hundreds chart.
  • Repeat this process with 34 +1 and 34 +10.
  • Guide a discussion about the pattern they notice when adding 1 and 10 on a hundreds chart (i.e. jumping one space to the right as opposed to jumping one space down)

Explicit Instruction/Teacher Modeling (20 minutes)

  • Tell students that today they will play a game where they will race a partner to 100 by adding 1 and 10 over and over again. Have the blank demonstration hundreds charts visible to all students.

  • Play against the students. One of the charts is for you to record on and one for the students to record on.

  • Have a student come up as a representative of the student team and roll the die in order to generate an equation. The first equation should begin with 0 so it will either be 0 + 1 or 0 + 10. They should write the equation on the board and then record only the total on the appropriate space on the hundreds chart.

  • Now it’s the teacher’s turn. Roll the die and generate your first equation and record your total on your hundreds chart.

  • On the students’ next turn, they should use their previous total as the first number in their next equation so that they are accumulating points. For example, if they had rolled a 1 previously and their equation was 0 + 1 then their next equation would begin with 1, either 1 + 1 or 1 + 10. They then should record their new total only on the blank hundreds chart.

  • Now it’s your turn again. Continue playing getting closer and closer to 100. As you get closer, the suspense builds because you need to get as close as possible to 100 without going over. If you go over you lose!

Guided Practice/Interactive Modeling

  • Split the class into pairs and have them play against each other. Each pair will need one die and two blank 101 and Out worksheets.
  • Circulate, helping partners record properly.

Independent Working Time (20 minutes)

  • Split the class into pairs and have them play against each other. Each pair will need one die and two blank 101 and out worksheets.
  • Circulate, helping partners record properly.

Extend

Differentiation

Support :For students who need more scaffolding, give them a hundreds chart with the numbers 1 through 100 written in and they can record by circling the new total.

Enrichment :For an extra challenge, have students play with a 1 to 6 cube. When they roll they can decide if they want to use their number as tens or ones. For example, a 6 can be used as a 6 or a 60.

Review

Assessment (5 minutes)

The worksheet is a great assessment. If students are adding and recording properly, it should be easy for the teacher to see what happened on each roll.

Review and Closing (3 minutes)

Faciliate a quick share-out on some equations that the students find particularly challenging and/or interesting.
