Introductory Activity (Warm-Up):
Read Amanda Bean's Amazing Dream and lead a discussion of how children count. |
Lesson:
Prior to activity, save the PowerPoint template Circles_and_Stars1 (File 1) and the Excel template total_stars (File 2) to your student shared directory.
1. Teach the children how to play Circles and Stars (complete directions are in Math by All Means, Multiplication Grade 3, page 28).
Have the children play several games using paper and pencil until they are familiar with the activity.
2. On a separate day, demonstrate on the computer how to copy a new slide within PowerPoint template called Circles_and_Stars1. Click on the slide to be copied, then INSERT, then choose DUPLICATE SLIDE. Repeat this step SIX times until students have a total of 9 slides.
On the first roll of the die, the student will make that many copies of the circles. To copy the circle, click on the circle. Click on Copy icon on toolbar (or right mouse click and select copy). Paste copy onto page using either icon on toolbar or right mouse click, paste. Student can repeatedly paste until they have the number of circles needed for their first roll. (If they roll a 1, they should click on the extra circle and touch the delete key to get rid of it.) This number should also be entered as the first part of their expression. Student 1 should roll and do their circles, then Student 2 will roll and do their circles.
3. On the second round of rolling the die, students will move that many stars into each circle. Six stars have been provided. Demonstrate how to copy and insert additional stars using the same technique as was used to insert the circles. Demonstrate how to record the second number in your expression. Show students how to use the letter x for a multiplication sign and where to find the = sign.
4. When students are playing the game, they can play in competition with the person next to them, each student recording their own information. The second partner cannot roll until he/she has checked his/her partner's work. Students can also play the game on wireless or student computers at a math center in the classroom.
5. To print, click on print. Select option for HANDOUTS and select 9 for Number of Slides per page. This will give you a one-page printout for each student.
6. Once students have printed their results, have each pair open the Excel file calledtotal_stars. Students should fill in their names and total stars for each round. They can then answer the questions at the top of the page.

Reteach:
To be determined by the teacher based on the student needs
|
Extension:
Have students compare their totals for each round. Which student won each round? Have them add their totals. Which student won the game?
Once students have mastered the single die version of the game, allow them to utilize two dice. Have students prepare an Excel spreadsheet of the different multiplication expressions they created. Was one expression more common than others?
|
Guiding Questions:
How can we accurately figure out the answer to our problem?
What is the difference between a group and the number of objects within a group?
|
Summary Questions:
How many rounds did you win?
How many rounds did your partner win?
Is it possible to win more individual rounds and still lose the game?
Was one expression more common than others?
What numbers are easiest to count?
If you could play one more round, would there be any way for the loser to win?
