Manipulating Minds in Math

3rd Grade: Students work to find the area of the composite figure by decomposing the shapes into smaller rectangles or squares. TEKS 3.6D Ten questions (10 composite figures)

Classroom anchor charts for LEGAL SIZE PAPER (8.5 x 14 in) Each Anchor Chart Includes: Attributes Vocabulary Diagrams Examples Non-examples 2-D Shapes Included: rectangle square rhombus triangle hexagon circle parallelogram trapezoid Focused on: Formal geometric language Variety of orientations

3rd Grade: TEKS 3.6C and 3.6D 12 task cards are included: 6 cards focus on TEKS 3.6C - determining the area of rectangles with whole number side lengths in problems using multiplication related to the number of rows times the number of unit squares in each row. 6 cards focus on TEKS 3.6D - decomposing composite figures formed by rectangles into non-overlapping rectangles to determine the area of the original figure using the additive property of area. Student response sheet is included. An

Each task card presents students with a list of attributes for either a 2-dimensional shape or a 3-dimensional shape. Based on the listed attributes, the students are challenged to create the shape and give the geometric name. All attributes use formal geometric language. Shape cards have also been included in case of differentiated learning and for students to match with the attribute challenge cards. 2-Dimensional Shapes Included: rectangle rhombus triangle circle square hexagon 3-Dimen

Review 2-dimensional shapes with students by playing "Scoot." This file contains 25 task cards, directional arrows, and a student recording document. 2-D Shape Review Shapes Included: circle triangle rectangle square rhombus hexagon Activities: Draw the 2-D shape What is the name of the 2-D shape? Describe the shape's attributes.
