LOVE THIS! 2 X 4 end pieces!!! The Instalation took about two days. We used a heavy bed of Bostic Best adhesive, 25 feet per gallon to act as moisture barrier and glue. Installed on 3/4 plywood on top of a crawl space. Pieces were 3/4 inch thick. My sons and I sanded, trowel filled with Glitsa wood flour fill, then poly sealed and gave two coats of Bona natural finish.
We finally began 2-digit by 2-digit multiplication this week! The kids are absolutely loving the matrix box we use to introduce 2x2 multiplication!! They love it because it's super easy. I love it because it shows them the place value involved in 2x2 multiplication. They can actually see the process of multiplying the ones and tens of one number by the ones and tens of the second number.
