Number Grid Game
A number grid game to practice determining a number that is 1 more, 1 less, 10 more, and 10 less than a given number.
This classroom game is great to use when students are learning to identify 1 more, 1 less, 10 more, and 10 less than a specific number.
This resource includes:
- number grid template
- number cards up to 1,000
- teacher instruction page.
The aim of this classroom game is for students to place the number cards correctly on the number grid template. For example, if they have the number 75 written on their number grid, they will need to find the 65 number card for 10 less, the 85 number card for 10 more, the 74 number card for 1 less and the 76 number card for 1 more.
This game makes a great math center activity when students are learning about place value or learning about number relationships found on a hundreds chart.
This resource is also available to download in black and white.
