What our Using Doubles to Add lesson plan includes
Lesson Objectives and Overview: Using Doubles to Add explains the concept of adding numbers up to 20 using the doubles strategy. The lesson is for 1st and 2nd grade students. There are several pages of content that explain this topic and provide examples. The activity, practice, and homework worksheets provide students the chance to exhibit their knowledge. Each worksheet will test students differently to ensure their complete understanding.
The lesson also contains suggestions in the “Objects for Lesson” section. These suggestions might aid you in your instruction of the material. For instance, you may have students use larger numbers if they have mastered doubles up to 10. Another option is to give students an odd number and have them work backward instead.
There are only two content pages of explanation. You can provide more examples of your own if your students need extra help. The lesson explains how to use doubles to add near doubles (two numbers that follow each other) more quickly. The lesson lists out the doubles equations from 1+1 through 10+10 for reference.
After the lesson, students will be able to play a game for the activity. The practice and homework worksheets will also test whether or not they have grasped the concept. If your students struggle to understand this strategy, give them some more examples. You may have to get creative in how you demonstrate this trick in action.
DICE ROLL ACTIVITY
The activity will be a really fun way for students to practice what they learned. The worksheet has a table of 28 spaces. Each space (except for the START and END spaces) has an equation, such as 5 + 7. Students will divide into partners as they play the game. They will take turns rolling a dice and moving their game pieces around the board. There are arrows to guide them in the right direction. On a separate sheet of paper, they will solve the problem of the space they land on. The game continues until someone gets to the END space.
SUM OF THE DICE PRACTICE WORKSHEET
The practice worksheet requires students to use the dice again. There are three columns on the worksheet: Number, Doubles, and Doubles Plus One. They will roll two die and find the sum of the two numbers. That number goes in the Number column. In the second column, they will write an equation doubling the number from the first column. After that, they will write an equation in the third column adding the first number and that number plus 1. If they roll 11, for example, they will put 11 in the first column, 11+11=22 in the second, and 11+12 in the third.
USING DOUBLES TO ADD HOMEWORK ASSIGNMENT
Finally, the homework will again assess students’ comprehension of using doubles to add numbers. First, they will fill in the table of doubles from 1+1 through 10+10. Second, they will answer a series of 18 equations using the doubling strategy.
