Rounding to Decimal Places and Significant Figures

Rounding to decimal places and significant figures math classroom activity

A bingo activity on rounding to decimal places and significant figures.

For this activity, questions are projected on the board. You can change the order of these if you want.

Comes complete with printable unique bingo cards for up to 36 students.
Alternatively, there is a no print option where students draw their own 3 by 3 grid and choose nine numbers from the board.

I have a collection of free math games and resources that you are welcome to access:
