I knew we were going to have to go back and review a lot of math with my son, but I had no idea how bad it would be.

This morning we did a simple story problem of 15x4. All of their math "reasoning" and arrays, and estimating has created a child who automatically does things like draw 4 circles with 15 dots each to solve this problem. :Crying:

We had to go over just stacking it up and doing the multiplication, or thinking through 15+15 is 30, which is 15x2, so 15x4=30+30=60. He kept being like ooooooh I see!!

then we talked about using those same skills for 18x2, thatthe best way is to stack it up and just do the quick and easy math, or without paper you think through it......

We know that 15x2 equals 30, and 18 is 3 more than 15, 3x2=6 so the answer is 36.

Yesterday to solve 6x6 he was drawing an array of 6 stacks of 6 squares.

I haven't bought a math book yet, I downloaded a unit with lots of games and word problems, and have just been using worksheets and the small whiteboard to review his math facts. But with as much work as we have to do in math I feel like I really need one.

I just don't know which one to buy. I have looked at all of them and not been able to decide which is best for this situation.

I plan to go back to the beginning of multiplication and try to re-teach it in a way that doesn't create a ton more work.

I would prefer mastery over spiraling, and minimal use of alternative strategies such as arrays, manipulatives are ok when introducing a new concept. Nothing too colorful or distracting, and a use of colors that takes into account the way your eye moves across the page.
