January 9, 2008: LESSON #7: ANGLES!!!
Angles are everywhere! Children can look all over the house and discover angles! Angles are made where 2 lines come together.
The angles children need to know in most states in elementary school are detailed below. Very young children (even toddlers) are able to differentiate between each of the types of angles. The chants were shown on Fox 31 News on January 9th.
#1) ACUTE ANGLES are angles smaller than 90 degrees. Where might children see acute angles? The letter V usually makes an acute angle. Go searching around the house for acute angles!
ACUTE ANGLES ARE...
OH SO CUTE!
#2) OBTUSE ANGLES are angles greater than 90 degrees and less than 180 degrees. The letter Y has obtuse angles.
OBTUSE ANGLES ARE...
OB-TUSE!
#3) RIGHT ANGLES are angles that are 90 degrees. The letter L makes a right angle. Right angles are the most common in homes. The corners where the ceiling meets the walls, the corners on doors, and the corners on tables are usually right angles.
RIGHT ANGLES ARE...
RIGHT LIKE THIS!
#4) REFLEX ANGLES are angles greater than 180 degrees and less than 360 degrees. To see the reflex angle, we must train our eye to see the exterior angle of an acute, obtuse or right angle. Reflex angles are introduced in upper elementary school. Younger children will have a hard time seeing these angles.
REFLEX ANGLES ARE...
OUTSIDE!
Now, what can moms and dads be doing at home to make children more
knowledgable and more comfortable with angles?
Here are some activities:
- The clock is a fantastic way to review angles with children, as the 2 hands constantly make different types of angles all day.
- Make an Angle Book! Staple 4 pages together. Get some tooth picks and glue, and you are ready to go! Decorate 1 sheet as the cover. Then, write "Acute Angles" at the top of the next page. Glue pairs of toothpicks all over the page, forming acute angles. On the next page, write "Right Angles" at the top. Continue gluing toothpicks on this sheet. The last page can be your "Obtuse Angle" page. Continue with gluing the toothpicks. If you don't have toothpicks or glue, children will ejoy drawing the angles, too! Or, if you are brave, try painting them!
- Have your child stand up. Play Simon Says. Each time you say, Simon says, follow with the name of an angle. For example, "Simon says, acute angle." Then the child chooses any joint to make an acute angle with (knees, elbows, etc). If you go fast, laughter is sure to follow!
