**Making Magic:**This game uses the knowledge of the meaning of the digits in a teens number as 10+ something to make the teens.**Jumping Ten:**Understanding the base ten place value system allows you to add or subtract ten from any number. This is a requirement for adding or subtracting 2-digit numbers mentally.**Going for Gold:**Focus is on the multiplicative structure of the number system, the repeated grouping in tens.
