93 – more baker’s choice

My algebra kids needed help starting this Linear-Programming problem. I referred them back to the Legos lesson, and that got the ball rolling for them. So here they are writing the inequalities for the problem.

92 – ASN in geo and baker’s choice in alg

I typed up these 16 statements from the geometry textbook for kids to work in groups and determine if each statement is Always, Sometimes, or Never True. It’s so lovely to hear the discussions among kids with these ASN activities. My algebra students are just starting the “Baker’s Choice” Linear-Programming activity. I asked them to write down all the information they would […]

91 – the prisoner and four herrings

Problems with a Point is a great website!  You can search for problems by TOPIC, HABITS OF MIND (STRATEGIES), MATHEMATICS BACKGROUND, TECHNOLOGY, or DURATION. “Open the Lock” is from the site, and I really enjoyed working on it (albeit there was hair pulling).  It’s challenging for my geometry kids, but the lively and thoughtful discussions that come out of the groups make it worth presenting. […]

89 – algebra review

I randomly assigned a problem from the Quarter Final to each algebra student to own and present the solution to the class. We had more students than problems on the exam, so kids were paired up for some of the problems. Students were supposed to ask questions of the presenters. I think it went okay […]

88 – (sub day) – quarter finals

GRRRRR!! I really hate being away from my classroom this often. I’ve lost track, but I think I may have been out close to 10 days already this year. The quarter ends tomorrow, so I had the sub give my Algebra and 6th graders their Quarter Finals today. We are on the last section of […]

87 – Legos and Hex game

I wrote about planning for this Legos lesson here. We really needed more pieces as a few of the students found the maximum profit within the first 5 minutes. I didn’t tell them that they did, so they continued to try. Then, I put the kids in groups of 3 and asked them to pool their Legos together […]

86 – Noah’s Ark and factor craze

Noah’s Ark is a great puzzle that I always do with my 6th graders. Mr. Noah wants his Ark to sail along on an even keel.  The ark is divided down the middle, and on each deck the animals on the left exactly balance those on the right — all but the third deck.  Can you […]

85 – Fermi and water balloons

I used to ask kids a lot of Fermi-type questions — for fun and for them to think about estimation and exponents and problem solving and finding answers to some key questions. Today’s question is on a much smaller scale than that which is typical of Fermi questions: How many water balloons would it take to […]
