Hi all! I have a demo lesson tomorrow morning for third grade for 30 minutes. I decided to do a multiplication review with Multiplication BINGO. I was going to hand out blank cards and have them fill in the products. I figured that 1-10 multiplication tables would be used. If someone gets bingo very quickly I thought we could keep going until someone fills the whole card. Do you think that will take 30 minutes? Take longer? Less time? It's for a class of approximately 33-35. Also - any ideas for a short review I could before hand maybe of the times tables to help fill up time? Any advice would be great. I'm bringing in all my own materials since I don't know what they have available there. THANK YOU!!!!!
