What teaching tool uses small wooden slabs with pictures to help practice basic math facts?

The use of small wooden slabs with pictures to help practice basic math facts fits well with the concept of puzzle cards. Puzzle cards can engage students through visual representation and interactive learning, making mathematical concepts more accessible and engaging. Typically, these cards can include images that correspond with mathematical problems or operations, allowing students to make connections between visual stimuli and mathematical concepts.

The other tools mentioned, while useful in teaching mathematics, do not specifically incorporate the idea of small wooden slabs with pictures for practicing basic math facts. Dienes blocks are tangible materials used for understanding place value and arithmetic but are not typically associated with wooden slabs with images. Geoboards are used for exploring concepts of geometry and spatial relationships through the use of rubber bands stretched over pegs but do not focus directly on basic math facts. An abacus is a counting tool that helps with basic arithmetic but does not include pictures or the slab format that puzzle cards offer.
