Grade 1+. Compact electronic unit takes the place of flash cards. Students select a level, then enter answers to displayed math facts. Positive and negative tones tell the student if the answer is correct, or mute for quiet play. Math facts answered incorrectly are asked again at the end of the run. Once all questions are answered correctly, players can view their elapsed time. The 3 x 3-3/4 x 3/4 unit features an LCD screen and a carabiner for easy attachment to a backpack. Requires 3 AG13 or LR44 batteries (included).
