Counting Caterpillar is appropriate for children ages 3-6. The app has three levels: easy, medium and hard. In easy mode, the child counts by ones to add segments to the caterpillar. In medium mode, the child practices in the same way by counting by 2’s, 5’s or 10’s. In hard mode, children are presented with a random number to begin counting from. In the app, your child must feed the aphids to the hungry caterpillar. After the correct number is fed to the caterpillar it is added as a segment to the caterpillar.The app rewards children with a butterfly after an exercise is completed correctly. This is a simple app designed to practice basic number concepts.
