Review Words:
hexagon
square
Use the review words to complete the graphic organizer.
Answer:
Explanation:
Above given figures are
Square : A Square is a flat shape with 4 equal sides and every angle is a right angle (90°).
Hexagon : A regular hexagon is a closed shape polygon which has six equal sides and six equal angles. In case of any regular polygon, all its sides and angles are equal.
Define It
Use your vocabulary cards to identify the words. Find each word in the word search.
Answer:
Explanation:
Cone : A cone is a three- dimensional geometric shape that tapers smoothly from a flat base (frequently, though not necessarily, circular) to a point called the apex or vertex. In the above figure, the arrow is pointing towards the apex or vertex.
Cube: A line segment formed where two edges meet. A cube has 12 edges. Because all faces are squares and congruent to each other, all 12 edges are the same length. In the above figure, the arrow is pointing towards edge.
Triangle: In geometry, a triangle is a closed two- dimensional shape with three straight sides. A triangle is also a polygon. In the above figure the arrow is pointing towards side.

Sort the Shape Sort Cards. Explain how you sorted.
Answer:
Explanation:
Sort the Shape Sort Cards means we need some shapes, we take print out shapes(in color) and then cut them out, or print shapes(black and white) on different colors of paper or card, cut them out, then mix them up. Or we might like to color them by our self. Now we have our shapes, let’s sort them by color. In the above figure we are given with shapes and shapes in color now we sort shapes according to colors as shown above.

Sort the Shape Cards means we need some shapes,
we take print out shapes(in color) and then cut them out,
or print shapes(black and white) on different colors of paper or card,
cut them out, then mix them up. Or we might like to color them
by our self. Now we have our three dimensional shapes, let’s sort them by
shape and name. In the above figure we are given with shape name,
now we sort shapes according to their names as shown above.
