This FREE app for the iPhone/iPad was developed by Scholastic for kids to practice, reinforce and extend their math facts. There are 12 levels in all – 7 addition and 5 multiplication. A chef places numbered plates of sushi on the counter. Kids have to combine the numbers on the plates to reach the target number (worn by the sushi monster). If the combination is correct, the monster gobbles up the sushi. If it is wrong, the monster throw a tantrum. Each round has 14 target numbers. Successfully completing one level unlocks the next. As kids progress through the levels they are expected to extend their thinking beyond the basic facts. At each level a strategy is provided to help kids succeed.

Common Core Standards met:

• 3.OA.7 – By the end of Grade 3, know from memory all products of two one-digit numbers.
• 3.NTB.3 – Multiply one-digit whole numbers by multiples of 10 in the range 10–90 (e.g., 9 × 80, 5 × 60) using strategies based on place value and properties of operations.

Great for math fluency – highly recommended!
