Mathematics, Operations (+, -, x, /, etc.)
Grade 1- 3
Children practice adding and subtracting with two-digit numbers. They also practice regrouping and use a calculator to check their answers.
Use the chart for the following activities:
The children need to pick three numbers on the hundreds chart that added together will make exactly 150. Each child needs to write down and add the three numbers to see if the numbers make 150. The children can use a calculator to check their addition. If the numbers make 150, the child uses a crayon to color in the three numbers. Then the next player takes a turn.
Variation: Pick another target number and play the game again.
Who Are My Neighbors?
Give each child a penny or a counter. The child throws the counter onto the hundreds chart and adds together the neighbors: the numbers above, below, and to the right and left of the counter. The child writes the math problem down on a piece of paper or in a math journal. Use a calculator to check the addition.
Variation (for 2 or more players): Each child follows the same rules outlined above, but after all players have taken a turn, the spinner is spun. If the spinner lands on "more than," the player with the largest number wins the game. If the spinner lands on "less than," the player with the smallest number wins.
Spill the Beans
Take three beans and toss them onto the hundreds chart.
On a piece of scratch paper or a math journal, add the first two numbers together and subtract the third number. Record the answer.
Variation (for 2 or more players): After each player has taken a turn, spin the spinner. If the spinner lands on "more than," the player with the largest number wins. If the spinner lands on "less than," the player with the smallest number wins.
