PostscriptĬoincidentally, a fourth-grade teacher wrote up his class’s explorations in equality today. If you have a school-aged child of any age, pose that task above. You can follow Tabitha’s and my adventures in equality in the coming weeks. The good news is this: If we are aware that children may develop the wrong idea about the equal sign, it is easy to help them to get it right. schools do worse on the task I gave Tabitha than younger ones do. Tabitha is in first grade, though, so she has lots of time to learn the correct meaning, right? (What button do you press to perform a computation on a typical calculator? The equal sign!)īut doing algebra requires that we understand the equal sign to mean is the same as or has the same value as. Arithmetic worksheets reinforce this idea. We train children to think that the equal sign means and now write the answer. Me: But that means it would be OK to say that 2 plus 2 equals 3 plus 1. Me: The equal sign means “is the same as”. T: A secret secret? Or not really a secret? Me: Does it make sense to say 2 plus 2 is the same as 3 plus 1? Me: Tabitha, I want to ask you a follow up math question. Later on, though, after putting on jammies but before toothbrushing, I follow up. I let it go and we move on with our evening. Me: What about this? Would it make sense to write 2 plus 2 equals 3 plus 1? Tabitha (7 years old): (reading aloud in a mumble to herself) Eight plus four is… She was working through some addition facts when it occurred to me that I had never asked her one of my favorite math questions. This plan worked beautifully for about five minutes. ![]() (Seriously, parents-you may mock me, but can you honestly say you haven’t tried something similar?) I could answer any questions she might have without opening my eyes. I would lie on the daybed on the porch with my eyes closed while she worked at the adjacent table. So I devised a plan the other evening when Tabitha needed to finish her first-grade math homework. Many interesting and productive projects, lots of interesting and challenging teaching problems. It has been a long, busy semester for me in my community college work. ![]()
