Grade: 1, Topic(s): mental number line

## Purpose

To practice number order by identifying number before, number after, or in the middle of a given number.

Give children practice with ordering numbers by playing this simple game. Choose a number from 1 to 12. Then call out “before _____,” “after _____,” or “____ is in the middle.” Call on volunteers to tell the number that comes *before* the given number, the number that comes *after* the given number, or in the case of* in the middle *the numbers that come* before and after*. You may wish to challenge children to give the numbers and check the answers.

Part 1 begins with identifying number *before* or number *after* with numbers 1 to 12. Part 2 incorporates is *in the middle* where children need to identify the numbers that come *before and after*. The extension moves to incorporate numbers to 50 with a specific focus on crossing decades.

I’ll call out “*before* ____” or “*after *_____” using numbers between 1 and 12 and you say the number that comes *before *or *after*.

Examples:

*Before*5 (4)*After*8 (9)*Before*10 (9)*After*11 (12)*Before*1 (0)*After*4 (5)*After*7 (8)

*While children are enjoying their building of mastery, feel free to repeat. When children are eager for more, try Part 2.*

I’ll call out “____ *is in the middle of*” using numbers between 1 and 12 and you say the number that comes *before and after*.

Examples:

- 8
*is in the middle of*… (7, 9) - 5
*is in the middle of*… (4, 6) - 7
*is in the middle of*… (6, 8) - 10
*is in the middle of*… (9, 11) - 3
*is in the middle of*… (2, 4) - 12
*is in the middle of*… (11, 13)

*As always, when children seem excited for a new challenge, move on.*

I’ll call out “*before*____, *after *____, ____ *is in the middle of*” using numbers between 1 and 50 and you say the number that comes *before, after, or before and after*.

Examples:

*Before*25 (24)*After*12 (13)- 19
*is in the middle of*… (18, 20) - 40
*is in the middle of*… (39, 41) *Before*30 (29)*After*19 (20)- 39
*is in the middle of*… (38, 40) *After*9 (10)*Before*20 (19)- 50
*is in the middle of*… (49, 51)

*Before* 40 (39)
