Evaluation for 5.4a
Materials provide opportunities for students to develop academic mathematical language using visuals, manipulatives, or other language development strategies.
Ingrade 5, materials provide visual supports to develop academic mathematical language. In "Count to Find Volume," students use real-world images (e.g., a cereal box, a tissue box,andafish tank) to determine which objects can be measured using unit cubes, applying vocabulary likevolumeandunit cube. Visuals, such as lines forming squares and everyday containers (e.g., a shoeboxanda suitcase), support the definitions of length, width, and volume.The materials use visual models and structured language supports to reinforce key mathematical terms. In "Recognize Place Value," students are shown a place-value chart labeled "Whole Numbers" and "Parts of a Whole"andfractional visuals (e.g.,1/10and1/100) to support the termstenthsandhundredths. The teacher guide prompts students to explain place -value relationships using specific language (e.g., "How many times more is a digit in the hundreds place than the same digit in the tenths place?").Students engage with visual representations and vocabulary in multiple lessons. In "Explore Attributes of 2D Figures," labeled diagrams of triangles, quadrilaterals, pentagons, and octagons support understanding of terms likepolygonandattribute. In "Round Decimals," number lines are used to represent decimal placement and rounding, with questions encouraging precise academic language. In "Model Multiplication of Fractions," students use images of partitioned baklava pans to represent fractional products (e.g., 1/4 × 1/2)and participate in aguided discussion to explain their reasoning.
