April
We have finished our Quadrilateral City Designs. They are posted outside of our classroom. Graded rubrics will be sent home when we return from break.
We will continue to work with geometric concepts including classifying triangles by sides and angles.
Students will also be introduced to angles concepts including but not limited to measuring and finding unknown acute and obtuse angles.
Other important vocabulary:
Rays, lines, line segments, parallel lines, perpendicular lines.
Try and help your child find these when taking a walk or reading a book.
We will conclude our geometry unit mid-April and begin our measurement and data unit by exploring a project called "Design my House" which will help students understand and utilize area and perimeter principles.
Standards covered in March and the beginning of April .
Reason with shapes and their attributes.
CCSS.MATH.CONTENT.3.G.A.1
Understand that shapes in different categories (e.g., rhombuses, rectangles, and others) may share attributes (e.g., having four sides), and that the shared attributes can define a larger category (e.g., quadrilaterals). Recognize rhombuses, rectangles, and squares as examples of quadrilaterals, and draw examples of quadrilaterals that do not belong to any of these subcategories.
CCSS.MATH.CONTENT.3.G.A.2
Partition shapes into parts with equal areas. Express the area of each part as a unit fraction of the whole. For example, partition a shape into 4 parts with equal area, and describe the area of each part as 1/4 of the area of the shape.
Draw and identify lines and angles, and classify shapes by properties of their lines and angles.
CCSS.MATH.CONTENT.4.G.A.1
Draw points, lines, line segments, rays, angles (right, acute, obtuse), and perpendicular and parallel lines. Identify these in two-dimensional figures.
CCSS.MATH.CONTENT.4.G.A.2
Classify two-dimensional figures based on the presence or absence of parallel or perpendicular lines, or the presence or absence of angles of a specified size. Recognize right triangles as a category, and identify right triangles.
CCSS.MATH.CONTENT.4.G.A.3
Recognize a line of symmetry for a two-dimensional figure as a line across the figure such that the figure can be folded along the line into matching parts. Identify line-symmetric figures and draw lines of symmetry.
