Skip Counting by 7s

The Skip Counting by 7s mat was designed to help students learn the multiples of seven and practice multiplying and dividing by seven.

Have your students start with the Pre-Test below. Then, spend some time jumping on the mat, using the activities below to guide you.

PRE-TEST

Before hopping on the mat:

Ask your child how many of these by problems they know. (Mark it off and try to remember for the final survey!)

7×1

7×6

7×2 

7×7

7×3

7×8

7×4

7×9

7×5

7×10

NOW, LET'S TRY SOME ACTIVITIES!

Have a student start on zero. Then, have them point out the pattern that the green boxes with the feet
follow. Explain to them that these boxes are showing the multiples of seven.

 

Whisper Loud: To begin learning multiples of seven, start with the whisper loud technique to have
students jump down the mat. Have students follow this pattern: Jump on the one. Whisper, “one.”
Jump on the two. Whisper, “two.” Jump on the three. Whisper, “three.” Jump on the four. Whisper,
“four.” Jump on the five. Whisper, “five.” Jump on the six. Whisper, “six.” Jump on the seven. Shout,
“SEVEN.” Continue with this pattern down the mat to seventy.

 

Skip Counting: Once they are more comfortable with the multiples of seven, you can have students
skip count down the mat, only jumping on the green boxes. Make sure they are saying the number
confidently and correctly when they land on each multiple. If their jumps get ahead of the numbers,
have them start again.

Give a student a multiplication by 7s problem (verbally, flashcard, worksheet, etc.).
Example: 7 x 6
The student will begin on 0. They will jump forward 6 times, only landing on the multiples of seven.
When they land on the sixth number, 42, they will say, “7 x 6 = 42.”

You can also have students practice each multiplication fact as they hop down the mat:
Jump on 7. Say, “7 x 1 = 7.” Jump on 14. Say, “7 x 2 = 14,” etc.

Give a student a division by 7s problem (verbally, flashcard, worksheet, etc.).
Example: 21 ÷ 7

The student will begin on the first number of the problem, 21. Then, they will jump back to zero on
the multiples of seven. How many jumps did it take to get back to zero? 3! Therefore, 21 divided by 7
is 3.

Give students a dividend that will have a remainder when divided by seven. Have them find and
stand on the dividend on the mat. Have them jump and count the number of spaces it takes to reach
the next lowest multiple of seven. The number of spaces is the remainder number. Have them hold
it up on their fingers. Then, have them follow the procedure for dividing while keeping the initial
“remainder” number on their fingers.

Example: Give them the number 37. They will find and stand on 37 and take two jumps to land on 35.
Holding 2 on their fingers, they then jump the multiples to zero, counting how many jumps it takes out
loud. When they get to zero, they recite, “Thirty-seven divided by seven is five remainder two.”

Line up two skip counting mats. Tell students you will be comparing these two factors and finding least
common multiples. Have one student on each mat. Instruct one student to hop on the multiples going
up their mat, shouting out the multiples as they hop. Then, have the second student do the same on
the second mat. When the class hears the second student call out a duplicate number, they yell to the
second student to stop. Check to see if they found the least common multiple (LCM) or just a common
multiple.


Example: Find the LCM of 6 and 7. Line up the Skip Counting by 6s and 7s mats side by side. One
student jumps 6, 12, 18, 24, 30, 36, 42, 48, 54, 60, up the mat. Then, the other jumps 7, 14, 21, 28, 35,
42...the class yells, “STOP!”
