Symmetry, Part 2
How can you tell if shapes are symmetrical? Fourth graders study 12 shapes, and draw lines down the middle of shapes that have symmetry. Once they are finished, they complete shapes that are missing their symmetrical sides. Some shapes...

Symmetry
Enhance your geometry lesson by working with shapes. Fourth graders follow lines of symmetry to complete ten shapes, most of them currently triangles. Have pupils color each half of their shapes to reinforce the idea of symmetry!
Curated OER
Lines of Symmetry, Shapes and Symbols
Which shapes are symmetrical? Third graders decide which shapes have lines of symmetry, and which shapes are not symmetrical. They work on 13 shapes and symbols, four of which have lines already drawn through them. Use this resource to...

Lines of Symmetry
Do your learners know that letters of the alphabet have lines of symmetry? Well, some of them do. Scholars examine nine symmetrical letters and draw in the line of symmetry for each (one of them has two!). They also complete six letters...

Dream Room Design
Junior designers brainstorm the elements that a bedroom might have, such as a bed, television, and dresser. They identify which items are needs and which are desires. They practice measurement skills in the classroom by determining its...
Curated OER
Symmetry
Is this the line of symmetry? Scholars analyze 12 images to determine whether or not the dotted line in each reflects symmetry. There are three examples for them to reference before they start, so consider reviewing these together before...
Curated OER
Line of Symmetry
Where is the line of symmetry in these shapes? Review this concept using the visual guide at the top of the page, explaining how some shapes have multiples lines. Consider demonstrating this concept with large cut-outs, physically...
Curated OER
Symmetry
Fold these shapes in half and you'll have perfectly equal sides. Kids explore symmetry by completing 16 abstract shapes which have been cut off at the line of symmetry. They draw the mirror image, using several examples as reference. An...
Curated OER
The Same
These monsters are only half-drawn! Challenge scholars to observe the line of symmetry and draw in the other half to reflect the first half. There are six simple monsters in all, and scholars can color them in once finished (encourage...
Curated OER
Symmetry
These symmetrical shapes are only half-completed, so scholars finish them by drawing the other side of the line of symmetry. Because your class won't recognize these abstract shapes, they will get authentic practice with this objective....
Curated OER
Lines of Symmetry
Drawing lines of symmetry helps scholars understand shape attributes, basic fractions, and equality. They determine how many lines each of these nine shapes has, using an example as reference. Consider having learners cut out a set of...
Curated OER
Symmetry
Where is the line of symmetry? Learners begin by drawing in a line to split three images evenly in half, using an example as reference. Encourage them to think about physically folding the picture to solidify this concept. Next, they do...
Curated OER
Symmetry
Do these dotted lines indicate symmetry? Some of them do, and scholars determine which ones in 12 different images. Because some of these are tricky, it may be helpful to have large versions of these shapes printed and cut out. This way,...

"Polly"gon Pockets
Explore polygons with your elementary learners. Divide the class in 12 to configure the polygon puzzle before them. They list the attributes of each type of polygon they see, and if there's time, they jump on the interactive website...

Pizza for Everyone
Pizza is the inspiration for the cross-curricular lesson detailed here. Start out with a poem about pizza and move into a discussion about balanced eating. To close the language arts portion of the lesson, ask your pupils to write...

Don't Fence Me In
Ensure that your class has a well-rounded understanding of new inventions, in this case barbed wired. Class members, after researching the history and development of barbed wire, assess its impact on cattle and the development of the...

A Field of Beans
Beans, or legumes as they are sometimes called, are the topic for an integrated multi-subject lesson plan. Youngsters will read, write, observe, and research everything there is to know about beans. They read a bean story, conduct a bean...
