These flashcards, based on the proven McGraw-Hill curriculum, will allow young learners to drill numbers and counting. Plus these cards take young learners one step further, by offering creative activities designed to develop critical thinking skills. A note to parents. Inside this box there are flashcards representing the numbers 1 to 50. On each card, you'll notice that the numeral is indicated, along with objects that represent the number in groups of five or less. Once your child masters number recognition in the lower range (1-10), you can guide your young learner to higher numbers by showing how the groups of objects can be counted by fives.
