Range Finder
Find the range of a given function. Write a function on a notecard and have students answer what the range would be. Function examples: f(x)=Square root of (5-x), f(x)=1/x, f(x)=2, f(x)=Square root of (4-x), f(x)=- 5
Domain Finder
Find the domain of a given function. Write a function on a notecard and have students answer what the domain would be. Function examples: f(x)=Square root of (5-x), f(x)=1/x, f(x)=2, f(x)=Square root of (4-x), f(x)=- 5
Elephant March
Make your elephant trunk with the brain gym hookup (arms out straight, put right arm over left and clasp palms together, then bring arms back toward body so that clasped hands are near your chin) Right ankle crosses over left leg. Whisper, ‘one‛. Left ankle crosses over right leg. Whisper, ‘two‛ Raise your trunk. Shout […]
Finding Pi
Use a string to measure the length of the diameter of the circle on the mat. Have the students measure the circumference of the circle in relation to the diameter. They will find out that the string goes around about 3 and 1/7 times. Explain that is why Pi is used to measure a circles […]
Obtuse & Acute Angles
Ask a student to lie down on the mat and make an obtuse angle or an acute angle with their limbs. Ask another student to make a different obtuse or acute angle that is smaller/larger.
Supplementary & Complementary Angles
Give students an angle measurement to make with yard sticks on the mat. Then ask what angle would be supplementary to it. What angle would be complementary?
Act It Out – Unit Circle
Give students different angles while they lie on the mat and make them with their arms and legs.
What’s an Angle?
Using the mat as a guide, help students recognize an angle is measured with reference to a circle with its center at the common endpoint of the rays and that its measure is related to how much of the circle is measured when divided into 360 “degrees”.
Tri-Angles
Material: Paper Have students make a large triangle out of a large sheet of paper. Then have them rip off the points, line them up on the mat (all pointing to 0) and ask what angle they make together. Have them make a triangle with different angle measurements (do not have to be exact just […]
Complement Me
Material: Yardsticks Have a student make an angle with the yardsticks on the mat. Ask a second student what the complementary angle is to the first. Do this with several different starting angles.
