MATH HELP: Strategies for visual, auditory, and kinesthetic learners.

VOCABULARY

P a r a l l e l lines – Have students write the word parallel. Have them circle the double lls in parallel. Explain how the two lls represent parallel lines: lines that will never intersect, cross, or meet.


Perpendicular lines - lines that intersect and form right angles. Have students write the letters of the word as such

Perpe

  • n
  • d
  • i
  • c
  • u
  • l
  • a
  • r

Next, draw a horizontal line underneath the letters 'perpe' . Then draw a vertical line in front of the remaining letters of the word. Connect the horizontal line to the vertical line to form a right angle. Help students to see how the letters intersect and form a right angle.


C i r c umference - Have students draw a circle around the letters c i r c in the word to help them remember that circumference is the distance around the outside of a circle.

Line segment - outstretch both arms evenly with both fists balled. Arms represent the line, while fists represent the endpoints of the segment.

Ray – outstretch both arms evenly with one open hand and one fist.

Acute angle – bend arm less than 90⁰ making a cute little angle.

Right angle – bend arm to form an L making a 90⁰ angle.

Obtuse angle – bend arm greater than 90⁰ making an angle greater than the acute and the right angle.

Quadrilaterals – Help students to learn the names of the quadrilaterals by remembering their p, q, r, r, s, t: PARALLELOGRAM, QUADRILATERAL, RHOMBUS, RECTANGLE, SQUARE, and TRAPEZOID. All quadrilaterals are parallelograms except trapezoids. (All q’s are p’s except t’s.)

Hexagon – Use the x in hexagon and the x in six to teach students that hexagons have six sides.

Have fun helping your students learn geometry.

      Thank you, Sherry. My students and I have had lots of fun learning these terms and meanings through modeling and association.

      I think these are really good tips for helping students to remember what these geometry terms mean.
