Today, using ClassFlow my class did an interactive math lesson/diagnostic on combining like terms. We started by classifying terms so that I could get an idea how students thought about numbers with integer coefficients and exponents.
Students came up with some super awesome and TOTALLY unexpected ways of classifying these terms. One student put the terms on a number line, but also alphabetically. It was fascinating. One that I will definitely be coming back to for more discussion. Some students put the numbers in order based on absolute value of the coefficient and then some students grouped them based on variable (like terms).
I’ll be honest, my students were so creative, it totally caught me off guard a few times. I’m not sure I consolidated all their ideas very effectively. It opened up a whole new way to start future conversations. From todays student responses we could have consolidated and moved our thinking along in the concepts of ordering integers, patterning and sequences or combining like terms. I forced the conversation to combining like terms. This is what we consolidated today, but I can’t wait to use their responses from today to take us into those other conversations at a later date.
At the end of the lesson today students created an Educreation video using their laptops or iPads and made their own “combining like terms” question in partners and then solved it while recording their steps. This provided an entry point for all students. Students still grappling with the concept created a question such as 1x + 1x = 2x. Students moving along in their thinking created a question such as 2x – 4y + 3x +7 = 5x – 4y + 7 . Within Educreations we can watch each others questions and how they solved them.
