Create Dictation of Sums (Monthly Subscription) Set your own numbers, choose the reading language (Japanese, English or Chinese), the speed and whether to include the opening phrase ("Start with." in English), then share the audio of each problem. MAIN FEATURES Abacus Addition and subtraction, then multiplication and division, step by step, with Review lessons along the way. Mental Calculation and Flash Anzan Picture the abacus in your head and practice Flash Anzan, Mental Sums, Mental Multiplication and Mental Division. In Flash Anzan, numbers appear one after another and you add them up. Dictation of Sums Listen to numbers read aloud in English. In the unit you answer from your head; the Dictation of Sums dojo is done on your own real abacus. Receipts Calculate while flipping through a pad of receipts. Times Tables Learn with the chart and song, then check each table with "In order", "Random" and "Fill in the blank". Number Play "Spot the Number", "Trace the Number", "Friends of 10" and more help young children get familiar with numbers, with the numbers read aloud.
