Looking for more math practice? Below, there are links to videos for all of the skills we are using this unit. After watching the video, there are practice problems provided, too!
4.G.1
I can draw and identify a point, line, line segment, and ray.
I can draw and identify right, acute, and obtuse angles.
I can draw and identify perpendicular and parallel lines.
4.G.2
I can classify shapes based on parallel or perpendicular lines.
I can classify shapes based on their angles being acute, obtuse, or right.
I can identify right angles and can identify whether a triangle is right, scalene, or isosceles.
4.G.3
I can identify line symmetry.
I can identify figures that have symmetry and can find the line of symmetry.
4.MD.5
I can explain how an angle is made of two rays with common endpoints.
I can explain how an angle is measured by its reference to a circle.
I can define and explain a "one-degree angle" and how it is used to measure angles.
I can explain how the measure of an angle is a multiple of the "one degree angle"
4.MD.6
I can use a protractor to measure whole degree angles.
I can draw an angle of a specified size, using a protractor.
4.MD.7
I can explain how when angles are joined in non-overlapping parts, the total measure is the sum of the parts.
I can solve real-world problems involving addition and/or subtraction to find unknown angles on a diagram.
