Symmetry for Smarties!

Sometimes you can learn from other bloggers! Today we watched a quiz about symmetry from 
The Smarties in Australia!

We got 100% on their quiz! Thank you Smarties!

Today we found objects with symmetry in our own room!

We took the Smarties Symmetry quiz!

A line of symmetry divides a figure into 2 congruent parts.

Congruent means:

  • same shape
  • same size
Check out our examples!








Yes! Yes! Yes! and Yes! A square has 4 lines of symmetry!

This pentagon?

One line of symmetry.

A ♥ is symmetrical!

We even looked at letters! Some were symmetrical and some were not!

Do you see any lines of symmetry in your house or yard?

  1. Dear Mrs. Yollis' Class,

    What a great experience being able to take a quiz that another class created. It's amazing what you can do with technology!

    There are so many great examples of shapes that have symmetry. I know when I was growing up, my playground had so many different lines of symmetry. My slide and swings each had one line of symmetry. My monkey bars had two lines of symmetry!

    Keep up your wonderful work!

    Your blogging buddy,
