3-digit Number Rectangle
Increase understanding and place value of 3-digit numbers tracking bricks in row, column and diagonal formations.
1. Find and read all the 3-digit numbers in the rectangle: they can be read in row, column or diagonal format.
How to prepare
• 1 base plate
• 9 random number bricks (some may be the same number)
• 1 number sign brick
Make a 3 by 3 grid on the base plate with the 9 bricks leaving spaces between for easier reading the numbers.
Place the number sign brick in the top left corner of the base plate to indicate the bricks are numbers.
• Tactile examination of the bricks requires more time than visual perception. Allow plenty of time for exploration!
• Ask “How can you make this activity more fun? More interactive?”.
• Ask “How can you play this activity with your friends?”.
• Change the number of bricks.
• Change instructions: read the 3-digit numbers backwards, find a prime number, the largest/smallest 3-digit number, a multiple of 5, only numbers that include the middle brick …
