Tracy Posted November 23, 2013 Share Posted November 23, 2013 My dh is a high school physics teacher. Yesterday, as an intro to series circuits, he posed the following question: What is the next number in this series? .3, .6, .9, . . . Less than half of his students got this right. And they are all Honors kids. So he wants to start including decimals in his classroom to see if he can remediate this problem. We are only barely starting decimals, so I don't have a lot of ideas for him. Can anyone suggest anything that he use in small spurts, or incorporate into his physics curriculum? Websites? Curriculum? Manipulatives? Would the Key to . . . series be useful for this? Any ideas would be greatly appreciated. Quote Link to comment Share on other sites More sharing options...
TarynB Posted November 23, 2013 Share Posted November 23, 2013 The Math Mammoth Blue Series contains two units dedicated to decimals. These are worktexts, so they contain both the explanations and the problems. They're perfect for remediation and review. I've used both MM and Key To, and I think MM's approach goes into the conceptual / "why do we do this" much better than Key To. Key To is good for rote practice after the concepts are taught elsewhere, though. http://www.mathmammoth.com/decimals_1.php http://www.mathmammoth.com/decimals_2.php Quote Link to comment Share on other sites More sharing options...
Walking-Iris Posted November 23, 2013 Share Posted November 23, 2013 I imagine it's slightly frustrating for a high school honors physics teacher to have to teach something they should have learnedin middle school. I'd say the Key To series would help. i really like what we've used in them so far. Quote Link to comment Share on other sites More sharing options...
dbmamaz Posted November 23, 2013 Share Posted November 23, 2013 my 10 wants to know what they thought it was . . . Quote Link to comment Share on other sites More sharing options...
Lolosoli Posted November 23, 2013 Share Posted November 23, 2013 I'm curious as well! What did the students that gave an incorrect number feel the answer was? Quote Link to comment Share on other sites More sharing options...
dbmamaz Posted November 23, 2013 Share Posted November 23, 2013 (the 10 yo assumed they said .12) Quote Link to comment Share on other sites More sharing options...
Jyniffrec Posted November 24, 2013 Share Posted November 24, 2013 Key To or Math Mammoth, as everyone else said. Quote Link to comment Share on other sites More sharing options...
