Supplementary or Complementary

Have a student jump down the mat and stop on either the supplementary space or the complementary space. When they stop, they shout out which one they chose. The rest of the students either lie flat on the floor (if supplementary) or sit up straight at a 90-degree angle (if complementary). This helps reinforce the difference between supplementary and complementary angles.

Grade 7

Angles into Triangles

Have students toss a bean bag onto the mat. Have them identify the type of angle where the bean bag landed. Then, challenge them: Can you form a triangle using that type of angle? They can work with two partners (lying down together to form the three sides) or use their fingers to model it. If the angle cannot be used to form a triangle, discuss why — and explore what makes a triangle possible.

Grade 7

Football Toss

On the Add/Subtract Mat practice patterns, multiples, addition or subtraction while kids have fun practicing their tossing and catching skills. Designate a quarterback and a receiver (students could take turns in the roles to involve the whole class) and give them an objective, such as count by 7s to 100. The receiver stands on 7, and the quarterback tosses them the ball. If the receiver doesn’t fumble, they move to the next 7, standing on 14. This continues until a receiver reaches 100 (a touchdown!) while the quarterback stays in one spot the whole time. If the ball is fumbled at any point, the receiver has to start back at the beginning.

Least Common Multiple – Factor Fun

Place two factors less than 12 on the edge of the mat. Ask students to find the prime factorization of both and place the corresponding cards onto the middle of the mat. If they share a number in common remove one of the duplicates (e.g. if there one number has two 2s and another has one 2 remove just one of the 2s.) Ask students to multiply all of the numbers that are left to get the Least Common Multiple.

Grade 6

Division by a Whole

Choose a unit fraction. Roll a die that will determine the divisor for the problem. Now, use small strips of paper, string, or electric tape to divide one of the pictures on the chosen unit fraction by that number. Count how many sections you made.

Grade 5, Grade 6

Exploring Fractions

Have students walk along the mat starting at 1/2. Make sure that they take time to observe and discuss the pictures on that space. You can introduce terminology through this exploration; for example, “One whole divided into two equal parts. It is called one half.” Continue this process across the mat for 1/3, 1/4, etc., making sure that students are vocalizing their observations.

Grade 2, Grade 3

Decomposition

Have a student toss a bean bag onto the mat. Look at the numerator of the fraction that the beanbag lands on and have that many students stand on the unit fraction, matching the denominator. For example: If the bean bag lands on 3/8 have three students stand on 1/8 to show that 3/8 is made up of 3-1/8ths. You can say, “Each of you is one eighth, so you equal 3/8ths.”

Grade 4

Hopscotch While Skip Counting by Twos

Have the student begin on START HERE. Have the student whisper “uno” while hopping with one foot on the numeral one. Then have the student jump with two feet on the two, clap and say “dos” in a loud voice (if your learning environment permits). Continue alternating between one foot and two-footed movements to the end of the mat. Repeat the activity until the student is comfortable with the activity. Be sure that your student says the numerals correctly. Tell your student the numerals if your student doesn’t know them.

Grade 1, Grade 2

Matching Numbers

Have your students match up the numerals with the same number of objects. Place one object on number one. Place two objects on number two. Choose two of the same thing—like two shoes, two books, or two toy cars. Place three objects on number three. Consider choosing three mittens, rocks, or spoons. Continue placing objects on the numbers! For bigger numbers like ten, try ten pennies, paper clips, or acorns. (If real objects are not available, try printing out images of common objects instead!)

Grade 1, Grade 2

Buddies

Have your students notice that all the numbers have corresponding dots. This is intended for students to learn the value of the numbers. Notice that the number two has two dots. These two dots are buddies. Two is an even number! The number three has three dots. Two of the dots are buddies, but there is one left over! Odd numbers have one left over. Three is an odd number.
