Maths Facts : number bonds

Great app! I noticed that in the multiplication facts that some right answers are marked wrong. For example, 6x?=60. I put in 10 and it marked it wrong. Same with 8x?=40. I put in 5 and it marked it wrong. Please fix that.

As a teacher who teaches Singapore math strategies, I was excited to see an app with number bonds and fact families. I wish that the fact triangles were set up the way we teach, though, with the large number at the top. This teaches that the two bottom numbers equal the top sum, and that the top number minus one bottom number gives the other bottom number as the difference. It's a great start, though.

One of the only apps I've found that let's my son explore number bonds and families and the Singapore Math Methodology. I like the new sound updates. It might be nice to add some sounds for navigation too. Also, a way to keep track of progress and see which groups your having trouble with would be cool. This could be the start of an entire line of apps. Multiplication and division, and even word problems, all teaching the Singapore Math method. Great Job!
