Interviewer:
Ha! I get this one! This is a lot less esoteric than some of your other cartoons. I was recently reading an article about how math humor can be useful in the classroom. I could see using this with students when teaching multi-digit subtraction.
Cartoonist:
When using with students, it might be good to ask them to explain why the 7 is asking the 5 for a “10.” Note that it’s better to position this as regrouping instead of “borrowing”. In other words, we want students to see 5 tens and 7 ones being equivalent to 4 tens and 17 ones. A cartoon like this can definitely be a good conversation starter.
Interviewer:
Good tips. Looking forward to more math conversation starters in next week’s Off the Number Line cartoon!
Check out how these 5 educators are using math cartoons in the classroom to engage their students.
