A 31 piece wooden base 10 math manipulative set, perfect as a learning aid for basic addition, subtraction, and place value. These are great for cementing mathematical thought in a traditional classroom setting, homeschool, or for tutoring and remedial math work.
Each "1" square is approximately a half inch (12mm) square, so the hundreds block is approximately 5 inches (12cm) square.
Includes the following pieces, the perfect amount for one student:
1's pieces (x20)
10's pieces (x10)
100 piece (x1)
These manipulatives are lightweight and easy for kids to use. They are laser cut from high quality 1/8" (3 mm) thick 3-ply birch plywood.
The base 10 pieces are suitable for use in their unfinished state but may also be finished. They may be painted, stained, and/or varnished without trouble. Some finish sanding may be required if you desire a very smooth surface.
When cutting wood with a laser, wooden edges are noticeably darker than the top and bottom. The darkening is fairly uniform and some people prefer the contrast. However, if you do not like the darker edges, they may be removed by sanding.
