Each card has a task on it (usually multi-step) and there are two different explanations for a solution. If you'd like to download the THIRTY pages worth of freebies featured above, please click the image below.
The students have to figure out which explanation is correct and then solve the problem. This freebie includes the two tasks mentioned above as well as anchor chart templates and printable posters.
(I have created ten pages of varying levels, and they are FREE for you to use with your students!
Click the link at the end of the post to access the freebies.) Each page is split in half.
Students always have to begin their written answers with "To solve this problem, I..." and they always have to end it with "Therefore, I know..." Students are always very tempted to say, "To solve this problem I added 1,098 and 530.
Therefore, I know the answer is 1,628 calories." Is this right? But is it the best answer and explanation they could have given? I always encourage my students to be VERY specific about what the numbers are that they are addressing when they write out their answer.The students put the directions back in order and make sure it all makes sense.They aren't actually having to do any math here, so it frees them up to simply think about the process. See link at the end of my blog post.) Once I feel like students understand the basics of solving multi-step problems, we move on to some scaffolded practice using these handy little foldables that I created!Students fold the paper in half, cut across the dotted lines on the right side, and fold the right flaps under.They always start with the left side, where they read the problem, following the CUBE steps (with a special place for the Examine step, because I think it is SO important), and then they open the flaps to reveal step-by-step how to solve the problem.I give them a completed multi-step problem with all of the steps out of order.The steps are written in the same format as described above, with very specific instructions walking the reader through how they solved the problem.Some students even like to create their own foldables (like those that I showed above) with the task cards!..when your students are really ready for an even bigger challenge, it's time to present to them... This is a new spin on Error Analysis that requires students to really analyze solutions and see which solutions and problem solving steps are the most reasonable.This also encourages students to restate the question in their answer and make sure they have actually answered the question that is being asked. ** It takes my students several examples to catch on to explaining their answers in this way, but it is so, so worth it once they truly understand.Here is another student sample: First, I have them do a little sequencing sort.
