Growth mindset and the value of mistakes in math learning
This article discusses brain plasticity -- or the huge potential for our brains to grow -- which means that EVERY student CAN learn math. Students need to have a growth mindset where they value mistakes and see them as opportunities for brain growth and learning.

Math Problem Solving Rubric

Instead of standing at the front of the room and teaching my kids how to do math---step by boring step—I pose a problem.  The kids work together and use their own strategies to solve that problem. It allows students to make sense of math and to build upon what they already know.

(1)  Mathematical process standards. The student uses mathematical processes to acquire and demonstrate mathematical understanding. The student is expected to:

Okay so you want to work backwards on this one. You know that she has 8 dollars left after she left the last store. So before she went into the last store, she had some amount of money divided in half minus two dollars that she then spent in the store. So you need to set it up as an equation. X=amount of money before the last store 8=amount of money when she left the last store Since she spent "Two less than half of what she had" you would set it up like this x/2+2=8 "Reads as X divided by two, plus 2, equals 8" then solve it x/2=6 x=12 so We know she had 12 dollars when she entered the last store. This makes sence, because if she spent half of 12 dollars (6 dollars) minus 2 dollars (4 dollars) she would have 8 left over just as the word problem described. Now you just repeat that same process for the other two stors. You know she had 12 dollars after she left the second store so you can set up the same euation useing 12 rather than 8. x/2+2=12 x/2=10 x=20 and then again for the first store. x/2+2=20 x/2=18 x=36 so you now know that she started with 36 dollars!

Actually, no, it s you who are wrong. In fact, those who answered.9999.. (or, prior to your correction, 99999.) are correct. If you never end the pattern,.33333. X 3 =.9999. Of course, this is equivalent (though not equal) to 1. You re assuming that the.3333. used to represent 1/3 is an accurate representation, but it is necessarily inaccurate, since 1/3 cannot be accurately represented in decimal notation. Don t call people wrong on a topic you re not an expert at, or you might just get schooled by someone who was a psych major and took upper level math for FUN.

Answers will be accepted until midnight, Eastern time, each Friday for each week's problems. Contest staffers attempt to send an e-mail response to participants' submissions within 36 hours.

If you supply a correct answer, your name, school, city, state and country (if outside the U.S.) will be displayed on the site under the current week's problem. Answers to past problems are not listed. One reason is that students and teachers have requested that we keep the past problems active. In other words, you can still submit answers to past problems.

The answer is C because 1/2 is 50% all u have to do is findthe other 50% of the 100. I automatically know that 2/3 is bigger than 1/2 so the answer isn t A 3/5 + 1/3 = 9/15+ 5/15 = 14/15 once again, too big 1/6 +1/3= 1/6 + 2/6 = 3/6 which simplified equals 1/2 There s your answer.
