These cards are a great introduction to multiplication. To construct:
Print the cards onto card stock or white paper.
Glue corresponding cards back to back (e.g. picture card showing 2 lots of 4 teddies glued to card that says 2 groups of 4).
Scatter the cards around the room along with concrete materials such as counters, teddies, unifix blocks etc.
Students make the array shown by the word or picture card and then flip the card to check their answer.
