Practice adding fractions with this free arcade style math game. Want to give us feedback on the game. Explain that a unit fraction is one of those parts.

3 developing understanding of the structure of rectangular. Compare two fractions with different numerators and different denominators eg by creating common denominators or numerators or by comparing to a benchmark fraction such as 12. Students who can generate equivalent fractions can develop strategies for adding fractions with unlike denominators in general.

As they work with shapes students think about angles investigate symmetry and compose and decompose larger shapes. 1 developing understanding of multiplication and division and strategies for multiplication and division within 100. 2 developing understanding of fractions especially unit fractions fractions with numerator 1.
