Book NRICH Bespoke PDBook Forthcoming EventsBook our Hands-on Roadshow Your Solutions Equivalent Fractions Equivalent Fractions have the same value, even though they may look different. These fractions are really the same: Why are they the same? Because when you multiply or divide both the top and bottom by the same number, the fraction keeps it's value. The rule to remember is: "Change the bottom using multiply or divide, And the same to the top must be applied" So, here is why those fractions are really the same: And visually it looks like this: Dividing Here are some more equivalent fractions, this time by dividing: Choose the number you divide by carefully, so that the results (both top and bottom) stay whole numbers. If we keep dividing until we can't go any further, then we have simplified the fraction (made it as simple as possible). You can make equivalent fractions by multiplying or dividing both top and bottom by the same amount.
Ask Dr. Math FAQ: Learning Multiplication Facts Some people seem to have real difficulty learning their multiplication facts. Parents, teachers, and students have written to Dr. Math asking for help with learning their multiplication tables (see some of the best answers from our archives). For an enjoyable twist, see also Russian Peasant Multiplication. There are many ways to help us remember such things, but what works best will be different for different people. Here's how this might work with multiplication facts. You can make a multiplication table. Since 1 times any number is just that number, we can leave the 1's off. Some people describe a row (or column) as "skip counting," so the row beginning at 5 is the row of "5 times" facts, or "skip counting x | 2 3 4 5 6 7 8 9 10 11 12 --+------------------------------------------ | 5 |10 15 20 25 30 35 40 45 50 55 60 These "times tables" can be memorized as a smaller chunk by themselves. Finding patterns A good way to learn multiplication facts is to look for other patterns in the table.

Integrating Math Into Other Subjects - Homeschool Blog at Homeschool.com This is an article from Homeschool.com’s newest e-magazine. The magazine is chocked full of great information-perfect for teaching preschool math–calculus. Math is the least liked subject for many homeschool parents and children. It can be scary, boring and frustrating. Here are some ideas to help you get started with integrating math into other subjects (you may notice that some of these cross over into several subjects): History: Write a report or complete a journal page on mathematicians (grab a FREE journal page at the end of this post).Learn about the history of clocks. Science: Art: Create a geometric greeting card using shapes that are congruent, similar, and equivalent.Examine works of art that incorporate geometric shapes.Create tessellations.Play with tangrams.Create a piece of artwork using perspective and proportion. Geography: Social Studies: Language Arts: Music: Technology: Examine the binary number system. Physical Education/Health: Everyday Life Application: Fieldtrips:
Creativity and imagination in the math classroom—reframing projects and project based learning | Curiouser and Curiouser This week was our monthly curriculum writing committee meeting. We were sharing our successes and challenges regarding the Common Core and I mentioned, “I don’t want to sound dramatic, but I hunger for creativity. I want my students to create.” I am truly afraid the kids will lose interest in math if I don’t give them opportunities to use their imagination. Jennie Winters, our Lake County ROE math/science coordinator, replied that according to PARCC performance tasks using creativity are one of the highest levels of performance indicators. So why have I limited my students’ creativity? If imagination is the single most important competitive advantage we can have today, (Thomas Friedman, Grinnell College 2009 commencement address) I should be fostering it in math. With that in mind, is it worthwhile to examine ways to demonstrate math mastery by combining it with a very different field the student has mastered such as art, music, language arts, social studies, etc?
