Daily Practice Problem:
Use mystery boxes to make the biggest sum with the following digits:
8, 2, 4, 7 (82+74, 84+72)
7, 9, 6, 5 (96+75, 95+76)
2, 3, 4, 5 (52+43, 53+42)
5, 5, 8, 2 (85+52, 55+82)
Pass out angle circles. Let students explore them for about a minute.
Making angles together:
-- Make a white angle that has more turning than a green angle.
-- Make a white angle that has less turning than a green angle.
Turn to p. 43 in your book.
-- Make angles on p. 43 independently.
Whose angle is bigger?
-- Use paper plate and paper angle circles to show that size of rays doesn't matter when comparing angles.
Angles in shapes:
-- p. 45: count angles in shape
-- Find shapes in our room: How many angles do they have?
-- I'll give you 30 seconds to count as many angles as you can. (go)
Go over homework:
-- Read questions aloud
* Is anyone confused about counting angles in shapes?
* Any time it says "in your classroom," replace those words with "in your home."
* #5: Write down what you found your angles on/in.
-- More practice with angle circles
-- Start on homework
- Can anyone make a 90° angle?
- Can anyone make an acute angle?
- Can anyone make an obtuse angle?
- Estimate the degrees of the angles you make with your angle circle.
