Included in this file are eight LCM Bingo cards, and a set of teacher "call cards".
Once students are ready, the teacher will call a phrase on the call cards. The answers are written in parentheses, and should not be called aloud.
An example of such a phrase would be, “The Least Common Multiple of 3 and 11.” Then, if the student has the number 33 on their cards, they would cover it with their marker, and wait for the next LCM to be called.
My preferred method of ensuring student accountability is to have students use lined paper from their math folder to show their work in. Additionally, placing counters over the call cards that you've used will prove a useful tool while trying to check the accuracy of winners claiming Bingo.
There are eight Bingo cards, with the numbers arranged in alternate patterns, so that not every child will call Bingo at the same time. Also included on each card is one Free Space.
I hope you enjoy them! Please feel free to customize my work, or ask any questions you'd like!
