2 Ideas for Use Group common words. Add a word that is unrelated to the group. Then work with a friend to name the unrelated word. Design a crossword puzzle. Use the definition for each word as the clues. A characteristic of a shape. Two rays sharing the same endpoint. How can a shape s attributes help you classify it? Imagine a friend showed you a drawing of two rays. Is the drawing an angle? Explain. Sample answer: If I can describe the sides and angles, then I can It isn t an angle unless the rays share an endpoint. tell what shape it is. A polygon with six sides and six angles. The point at the beginning of a ray. Compare a hexagon with a right triangle. Use the space below to draw your comparison. Endpoint is a compound word made of the words end and point. What is another example of a compound word? Lying the same distance apart from one another. Name an example of lines that are parallel that you might see during a walk down the street. Sample answer: The yellow lines Sample answer: snowman A polygon with eight sides and eight angles. Read and solve this riddle: I am an ocean animal. The prefix oct is a part of my name. I have eight legs. What am I? octopus in a crosswalk. A polygon with five sides and five angles. Complete this sentence with a chapter vocabulary word: Five sides and five angles are called of a pentagon. attributes A quadrilateral that has both pairs of opposite sides parallel and equal in length. What is the root word in parallelogram? Use it in a sentence. parallel; The sides of the window are parallel to each other. See students drawings.

4 Ideas for Use Write a tally mark on each card every time you read or write each word. Challenge yourself to use at least 3 tally marks for each card. A shape that has four sides and four angles. What does the prefix quad mean? four Draw or write examples for each card. Be sure your examples are different from what is shown on each card. A closed twodimensional figure formed of three or more straight sides that do not cross each other. Use a dictionary to find the meaning of the prefix poly. How does it relate to the meaning of polygon? Sample answer: many; A polygon is a shape with many sides. A parallelogram with four right angles, opposite sides that are parallel and of equal length. Draw a rectangle. Then partition it into 3 equal areas. Write the fraction that describes your drawing. A part of a line that has one endpoint and extends in one direction without ending. Write a sentence using another meaning for the word ray. I saw a ray at the zoo s aquarium. See students drawings. Give three examples of right angles in a classroom. A parallelogram with four sides of the same length. Explain how a rhombus and square are alike. Sample answer: the corner of the Sample answer: They both have door, the piece of paper on my desk, the poster on the wall four sides of equal length and both are quadrilaterals. A parallelogram with four right angles and four sides of equal length. A triangle with one right angle. Explain how a square and a trapezoid are similar. The prefix tri means three. How can you use this to help you remember a triangle s attributes? Sample answer: Both are Sample answer: Triangles always quadrilaterals. have 3 sides. An angle that forms a square corner.

6 Ideas for Use Write the name of a lesson on the front of a blank card. Write a few study tips for that lesson on the back of the card. A polygon with three sides and three angles. Imagine your friend draws a shape with three sides and three angles. How would you classify the shape? It is a triangle. Use the blank cards to draw or write examples that will help you with concepts like the relationship between quadrilaterals and parallelograms. A quadrilateral with exactly one pair of parallel sides. Explain how a square and a trapezoid are different. Sample answer: A square has 2 pair of parallel sides. A trapezoid has 1 pair of parallel sides. The prefix peri means all around. How does this help you remember the definition of perimeter? Sample answer: A perimeter is the distance around a shape. The shared endpoint where 2 rays meet in an angle. Vertex can mean the highest point of something. How is this similar to the math meaning? Sample answer: Both are about something coming to a point. The distance around the outside of a figure.
