Place hoops down in a large outdoor area or gymnasium to create a large circle.
(See modification #3 to adjust for inside a classroom.)
Label hoops with 0, 10, 20, — 100
(not putting the hoops in chronological order encourages more fitness).
- Scatter the “in between” numbers all around the inside of the hooped-off area.
Tell students that they will be practicing rounding today in conjunction with fitness.
On the “go” signal students will skip (or whatever locomotor skill you choose) to collect a number from out of the center of the circle.
When they get a number, they look at it, round it to the nearest ten and then decide which hoop it belongs in.
After finding the hoop and putting the number in it, they will skip back out to the center, pick another number and repeat the process.
- When all of the numbers are gone, the teacher will take the students to each hoop and see if the numbers are in the correct location. If they are not, the class will discuss why it does not belong and where it should go.
Remind students they are only picking up one number at a time.
Have different students begin at a specific hoop, so they at least know where one of the major numbers is located and so they are spread out.
Underline numbers that when upside down make another number or look like another number. Examples:
Do this with partners or groups of three, so not everyone is in the middle at the same time. Have one student go out, get a number and place it in the correct hoop, then come back and hi-five their partner and then that person goes in.
Use this same game with decimals or rounding to a specific hundred/thousand, in a number of millions.
- Stay inside and place paper plates down that are labeled 0-100. You can even use the tops of student desks.
