Designed for use with our Ladybugs Counting Stones, these beautifully attractive activity cards are an ideal way to encourage children to develop early math skills. The detailed, photographic images will inspire much talk as children explore early number through matching, counting and ordering. They will also explore odd and even numbers and number bonds/pairs. Made from durable plastic the cards are tough enough for use in the outdoor area, the natural environment for ladybugs! Each set includes 16 colorful cards measuring 8" x 11".
