@insertcrestivename Lol. I think it says 10, but it's non backlit LCD and so can be hard to read from certain angles and lighting. Also the screens get "burn in" when old and show phantom images where lines have been shown many times. I still laughed though so upvoted.
It's called "Twist and Shout Addition" (as it says.) it's made by Leapfrog. Leapfrog started in 1994 so anyone that used it must have been born after 1994. When I was learning to add we had little blocks and worksheets.
Born in 1992 and I definitely played with this growing up. I think they had a multiplication one too... or subtraction. It was like "Bop It" for learning!
I worded that wrong. Not born after 1994, born in a range where they were the standard age group to learn basic math after 1994. It seems they had subtraction, division, multiplication, and division versions of this.
We used to build little houses and what not with those. They didn't have those until I was a little older so we might have gotten them a year or two. Before that we had wooden blocks including ones of different shapes to teach basic geometry.
What is that?
edit: Apparently they're still available... http://www.hand2mind.com/item/base-ten-blocks-classroom-kit-set-of-1610/1226?green=F275232D-CB22-5849-0C26-60E9034636A5
