Evaluation for 5.4a
Materials provide opportunities for students to develop academic mathematical language using visuals, manipulatives, or other language development strategies.
In theLesson Idea "A Treehouse of Cards," the materials provide visuals to help students develop academic vocabulary. To understand the terms multiplication and product, the materials show five groups with three birds in each group. The program then relates that problem to the standard algorithm, 5 x 3 = 15.In theLesson Idea "Shape Partitions," students use geometric shapes to explore fractions as any part of a number, group, or whole. Using models, students use the academic language: fraction, shape, partition, halves, thirds, fourths, fifths, and sixths to describe a fraction.In theLesson Idea "2-Dimensional Shapes," students explore quadrilaterals and their properties using geometric shapes. Using models, students use the academic language: classify, quadrilateral, two-dimensional, square, rectangle, rhombus, parallelogram, trapezoid to identify similar and different properties. Students then create a visual flipbook to outline each quadrilateral and its defining characteristics.
