Mathematical markers, 5-part set, teaching aid

Mathematical Markers Educational Set, 5-piece set, an educational tool developed in collaboration with a clinical speech therapist. Includes printed felt wheels and ovals on a wooden rod, with mathematical symbols: Plus, Minus, Equals, Is bigger, Is smaller. The simplicity of the signs in conjunction with verbal expression can be very well used to practice pre-math ideas or math skills already in preschool, in younger school age or in special education.
