In March , the National Mathematics Advisory Panel listed skills that elementary students need to master algebra down the road:
· By the end of grade 3, they should be proficient in the addition and subtraction of whole numbers.
· By the end of grade 4, they should be able to identify and represent fractions and decimals and compare them on a number line or with other common representations of fractions and decimals.
· By the end of grade 5, they should be proficient in multiplication and division of whole numbers; in comparing fractions and decimals and common percents; and in the addition and subtraction of fractions and decimals. They should also be able to solve problems involving perimeter and area of triangles and quadrilaterals having at least one pair of parallel sides.
