Find the robber - neat little game!

You get to practice coordinates and logical reasoning -- where does the robber hide? In how many guesses will you locate him?

After you guess, the game gives you the distance from your guessed point to the robber's location.

Fun and fascinating!

Someone asked me about the BAR MODELS in the problem solving lessons in grade 5.

This person said that they had just completed every problem in the lesson Problem Solving with Bar Models 1, but her son is still having a hard time knowing how to make the bar model after reading the problem, and knowing what to do with the fractional part once it is figured out.

She was wondering if there was something else for supplemental practice, and if she should look for mastery in this area at this point.

MY ANSWER:

I feel it would be good to achieve some degree of mastery at this point (in 5th grade). I suggest using this website for additional practice:

http://www.mathplayground.com/thinkingblocks.html

- in particular the "Multiplication and Division" and "Fractions" subsections.

Also, if this is difficult, consider spreading out the study of these lessons in Math Mammoth by starting the child simultaneously on the next chapter. For example, one could study problem solving every other day, and the next chapter every other day. That way, if it's spread out to a longer period of time, the student's brain has more time to "mull it over". :)

I hope this advice helps the person who asked -- and maybe some of you others out there also!

It's probably that time where many are teaching the multiplication tables to their children or students. :) Check out

=> http://www.mathmammoth.com/lessons/multiplication_tables.php

for a guide of how to teach them. And here's a link to videos that do the "structural" (not totally random) drill for you:

http://www.mathmammoth.com/videos/multiplication_tables.php
Learn the multiplication tables with these video lessons. For each table, the videos teach the skip-counting pattern, the table itself (structured drill), and the table BACKWARDS.

Yeah! 2017 Mathematics Game is here!

If you don't know what it is, it's a number "game" or challenge where you build each of the numbers from 1 to 100 using the digits 2, 0, 1, and 7 -- and you HAVE to use all those digits!

For example:

10 = 2 + 0 + 1 + 7

8 = 2 x 0 + 1 + 7

7 = 2 x 0 + 1 x 7

...and so on. I'm sure you get the gist!

Read the complete rules for this game at:

Two of the most popular New Year’s Resolutions are to spend more time with family and friends, and to get more exercise. The 2017 Mathematics Game is a prime opportunity to do both at once. S…

An easy lesson on how to calculate the percentage of change (percentage of increase of decrease). It really is very simple!

I enjoyed reading this article...

http://www.mathcoachscorner.com/2016/02/using-guiding-questions-to-probe-student-understanding/

The author, Donna Boucher, discusses "GUIDING QUESTIONS" in mathematics. Those are questions you ask the students that probe their general understanding of a concept - and most of the time they seem simple to us. :) For example, she asked some 4th grade students, "What are fifths?" and got surprising answers -- showing MISCONCEPTIONS in the students' thinking.

It reminded me of a conversation I recently had with my 2nd grader. It's not about math, but you'll see the similarity. We had been discussing weather. He had some idea that in some countries the weather was colder than where we live. So, I asked him, in front of a big world map, in which places did he think the weather was warm and where it was cold. :O

I got a pretty surprising answer... he pointed to the Americas as being the warm places, and then Europe, Africa, and Asia were cold. His "division" of the world to warm/cold was with a vertical line through the Atlantic!

But in another sense, it's NOT surprising... it reflects what little bits and pieces he's learned. He's heard Finland is cold, and his school book had pictures of snowy weather from Russia, so that probably was the major factor in his decision to delegate all of the Eastern hemisphere as chilly places.

You can do the same in ALL your teaching, and Donna has some great ideas of how to get started when it comes to math. Please do go check out her article! It's not long.

Affordable, quality math books, loved by parents, homeschoolers, and teachers.
Introduction
Math Mammoth offers affordable, yet quality math worktexts and workbooks for grades 1-12. The books are available as both downloads, and most also as printed books.

Math Mammoth books concentrate on conceptual understanding and are strong in mental math. The directions in the worktexts are written directly to the student, and are often self-teaching, thus requiring little preparation and involvement from the teacher.
