Clever Catch®
GEOMETRY I
Your Geometry I Clever Catch® provides an excellent way for children to practice geometry.
There are 73 color coded questions included (Green = Coordinate System, Yellow = Planes, Lines,
and Angles, Blue = Quadrilaterals, Orange = Triangles). Clever Catch® can be used at school in
organized classroom activities. It can also be used on the playground or at home. Grades 9+,
Ages 14+.
CLEVER CATCH® AT HOME OR ON THE PLAYGROUND
Basic play for Clever Catch® is simple. Two or more players toss the ball to each other, answering
the problem underneath or closest to their left thumb. Each problem is numbered and enclosed
in its own space, assuring the child will know which problem to answer. Answers are provided in
this insert for independent play by students.

Any point that lies on the perpendicular bisector of a segm
ment
is ____ from the endpoints of a segment.
Equidistant
Pairs of children toss the ball back and forth for one minute answering problems.
A scorekeeper tallies which team has the most correct answers in the time limit.
67.
If one angle of a parallelogram is a right angle,
what kind
d of parallelogram is it?
A rectangle

70.
What are two properties of a median of a trapezoid?
1) It is parallel to the bases;
2) Its length is equal to half the sum of the bases.
71.
Two non-vertical parallel lines have _______ slopes.
Equal
72.
A plane exists in how many dimensions?

What relationship do the diagonals of a rhombus have to
the
e angles which they intersect?

73.
BEAT THE CLOCK:
The entire class plays cooperatively as one team, trying to better its own time and number of
correct answers in each game.
DIRECTIONS:
1 Choose a timekeeper. You also will need a monitor - teacher or student - to keep track of correct answers.
2 Divide the class into two lines of equal length, students facing each other.
3 At the timekeeper’s signal, toss Clever Catch® to the first student. As quickly as possible, this student reads and answers the problem underneath his/her left thumb.
4 This student then tosses Clever Catch® to the student directly across from him/her in the second line. This student reads and answers the problem under his/her left thumb.
5 Play continues until all students in both lines have had a turn. When the last student has answered, the time and correct number of answers are recorded.
