Double sided self-check reusable Mats – Math’s
These interactive learn and play mats feature an intriguing self checking technique that creates interest and enjoyment while encouraging children to learn to learn Math’s. Use dry wipe markers to write the answers. The temperature sensitive ink fades to reveal the answers when the body heat of a child’s finger is applied by rubbing the magic black block. When the temperature decrease the magic block will turn black again! A fun way to self check and learn.
