Many students struggle with all the properties of quadrilaterals. It doesn’t help that so much symbolism needs to be instantly recognizable in this unit. The flash cards below can help them make sense of the symbolism, recall the definitions/theorems, and can make learning more interactive.
There are 30 flash cards included with this set. Copy pages 2-3 back to back and 4-5 back to back on card stock. (Your printer will warn you the margins are small. Override the error message.) This gives your students the opportunity to write the definitions and theorems, helping their recall. Alternately, print 6-7 and 8 -9 back to back to give them flash cards that are already filled out.
This set includes 6 cards that name quadrilaterals with special characteristics. Your students can use them to sort and organize their cards.
