Make Tens

Have students choose a number to stand on. Ask each child how many steps to make a number with 0 in the ones place. For example, if a student is standing on 33, they will figure out how many steps to make 40.

Dicey Doggy Days

Play Dicey Days with a die that goes from 1-10 or 1-20

Grade 2, Grade 3

Dicey Days

Each student selects a card with a number from 1-99. All students go to the mat and each student stands on their number. Instructor rolls a plus/minus die and a traditional die. The students add to or subtract from their number based on the results of the roll of the dice.

Grade 2, Grade 3

The Card Rules

The game is played in pairs. Two cards are drawn from the pile and each student receives one card. The students decide who will stand on the mat and who will give directions. One student stands on the mat on the number that is on their card. The other student directs them based on the second card but does not reveal the number. The goal is to direct the student on the mat to the second number with directions such as add 2, add 30, subtract 4, or subtract 50. When the student on the mat reaches the new number, the students switch places.

Grade 2, Grade 3

The Dice Decide

Each student chooses two cards from a pile of numbered cards and chooses one of the numbers to stand on and the number on the other card is where the student is trying to move to. Once the student stands on their number, they hand that card to their teacher. The object of the game is to be the first to move to the number on the card that the student is holding. The acceptable movements are based on the roll of the dice. If a 6 and a 4 are rolled, then the student can choose to add or subtract 6, add or subtract 4, add or subtract the sum, difference, product or quotient of 6 and 4.

Terrific Tens

Write +10, -10, +20, -20, +30, -30, +40, -40, +50, -50, +60, -60, +70, -70, +80, -80, +90, -90 on index cards. Have students stand on mat. Choose a card from deck and call out the number and direction (e.g. +80 is read add 80 or -30 is read subtract 30).

Grade 2, Grade 3

Sieve of Eratosthenes

A prime number is a natural number that is greater than one and only has two factors, one and itself. Use the Sieve of Eratosthenes to find all the prime numbers up to 99.
1. Stand on the number one. One is special—it is neither prime nor composite.
2. Step to the number two. This number is prime. Skip count by twos, covering all
the multiples of two with black construction paper.
3. Move to the next number that is not covered with construction paper (in this case
it will be three). Skip count by threes and cover all the multiples of three with black
construction paper.
4. Continue the same pattern until one hundred. The numbers not covered in black
construction paper are the prime numbers.

Grade 6

Stupendous Square Roots

Follow the directions for Super Squares activity. After each square has been created, ask “what is the square root of the square number 4, 9, 16,” or whatever square number you are discussing. The square root is the number of rows or columns that make the square number. Ask “Who can figure out the square root of 25, 49, or 81?”

Grade 5, Grade 6

Super Squares

Put black construction paper down on the numbers 1, 2, 11, and 12. This makes a 2×2 square and the square number four. Have students count the four squares to discover that 2×2 is actually 4. Ask “What is the next square number? Who can guess?” Students can find the answer by covering the 3 by 3 square (covering the numbers 1, 2, 3, 11, 12, 13, 21, 22, and 23. Have the children skip count by threes, to discover that 3×3 is nine.

Continue laying down pieces of black construction paper to make additional square numbers.

Grade 4, Grade 5

The Tens Traipse

Begin by starting at zero. Add ten and step on that number. Continue throughout the 90 number grid. Next take the Tens’ Traipse backwards from 90. Afterward, take the Tens’ Traipse going forward or backward starting at any number.
