Click the "PLAY" button after opening the link.
Pick two teams and a grid size of 24.
Choose "CLASSIC" or "Classic Jr with easy power ups".
Decide who will be player 1 and player 2.
Take turns picking a question and solving it in your
notebook.
6. Click "OKAY" if the player is correct, and "OOPS" if not.
7. The winner is the player with the highest score.
This game works like 'Simon Says'.
1. All students stand up.
2. Students create angles using their arms, body or legs.
3. Students must listen for the type of angle you need to
make.
4. If the teacher does not say "Teacher says" prior to
the angle called, students should not move. If a student
moves without the teacher calling "Teacher says", the
student must sit down.
This game works like 'Simon Says'.
Types of angles to call:
1. Acute
2. Right
3. Obtuse
4. Straight line
5. Reflex
This game works like 'Simon Says'.
