For those of you who have been followers of mine for some time, you know that I am a HUGE fan of using concept sorts in my classroom! There are SO many skills that are reinforced with this activity…from developing math understanding to developing mathematical discourse skills to logical thinking to cooperation to error analysis. The amazing thing? You can accomplish all that in less than a half hour! I have worked with concept sorts all year and my students have made incredible gains in their ability to think through and discuss the concepts presented–whether it be features of geometric figures, fractions, equivalent to 1/2, or angle size.
|This sort was perfect after we had learned about parentheses and that a number next to a variable means “multiply the two”|
|This challenging sort led to great discussions…these values of “n” have solution sets of more than one number! Students loved trying to find which solutions sets matched each expression!|
|The students often write directly on the cards to “prove” their thinking and to help check for errors.|
