Quick Images is a great game to play to help children practice subitizing - quickly seeing how many in a small set. As children gain experience, talk about seeing smaller number groups in larger sets. For example, “I saw a group of two dots and a group of three dots and I knew that was five!” Each child might “see” how many in a different way.
To print at home: There are 7 types of cards in the dot card deck. Each type of dot card can be printed separately on colored paper. We have suggested these colors in the directions, but you can use any paper available to you. For example, you can use blue paper to print the blue circle dot cards.
