Matching Game – Prime Numbers

Write out two sets of numbers including all of the primes from the mat and several composite numbers. Have two teams of students turn over the cards at the same time and try to be the first to choose out the prime numbers. Once they think they have found them they run and check themselves […]

Target Number

Have one student stand on an integer on the mat. Have another student give them a target number and a third student pick the sign of the given number (+,-). The student on the mat then figures out how to get to the target number mentally or by jumping on the mat and then announces […]

Compare

Have two students each pick a number on the mat and stand on it. Have each state the comparison between their two number. e.g.Standing on -6 and -3. The one on -3 would say, “-3 is greater than -6.” and vice versa. Point out that it is the one that is closer to positive side […]

Absolute Value

Have a student stand on a negative number of their choosing. Ask them what the absolute value is of that number. Then ask them to jump to that number counting their jumps, first counting down to 0 from where they are standing and then when they pass zero count up until they reach the absolute […]

Opposites

Have one student stand on a positive number on the mat. Ask another student to stand on its opposite. Have both students jump to zero while each counting their jumps simultaneously.

Adding Thousandths

Take a thousandths block. Figure out where to put the thousandth block on the mat. How do the numerals at the top of the mat change after a thousandth has been added to the thousandths place? Continue adding thousandths until there are ten thousandths blocks. What happens to the hundredths place? What happens to the […]

Prime Factorization

Pick a composite number and place it at the top edge of the mat. Have students find two factors for the number. If the factor is a prime number, leave it face up. If it is a composite number, find two factor cards of it and place them beneath the composite factor on the mat, […]

Not a Factor

The teacher places products around the edge of the mat. Students try to fill the board with numbers that are not factors of their corresponding products.

Find My Products

As a challenge, have one group of students set up the entire board, first laying out products in the middle, then filling in the factors along the edge. When complete, have them remove all of the product cards from the board. Have a second group of students try to figure out what products were there […]

Greatest Common Factor – Factor Fun

Place two products on the edges of the mat (e.g. 24, 18). Have students place the prime factors of 24 beneath it in the factors squares. (Break down larger factors as needed.) Then ask if any of those factors are also factors of 18. If they are leave them on the mat, if not take […]
