Develop Understanding of Fractions

SCAFFOLDS

SUPPORTS

Students develop an understanding of fractions as numbers with 2, 3, 4, 6, and 8 as denominators. This includes understanding unit fractions as one part of the whole written with a numerator and denominator (3.NF.1, 3.G.2). Students represent a fraction as a number on a number line (3.NF.2), understand fraction equivalence with visual models and number lines, and compare two fractions with the same numerator or same denominator (3.NF.3).

Students partition circles and rectangles into two, three, or four shares and describe the shares using words such as halves, thirds, etc. (2.G.3)

Arrays

Solve Problems Involving Measurement

SCAFFOLDS

SUPPORTS

Solve problems involving measurement and estimation of intervals of time, liquid volumes, and masses of objects. (3.MD.1), (3.MD.2). Recognize area as an attribute of two-dimensional regions and relate the concept of area to multiplication and addition (3.MD.5), (3.MD.6), (3.MD.7). Solve real world and mathematical problems involving perimeter and area (3.MD.8).
