Lesson: Multiplication and Red River Carts

Standards Summary This lesson is just a final review of multiplication before heading on to division. Our last lesson was all Ojibwe history. For a little variety we combined social studies and math today. Did you know you can also play Making Camp offline on your tablet or phone? Well, you can. You can play

What are Fractions?

Standard: CCSS.MATH.CONTENT.3.NF.A.1 Number & Operations – Fractions: Understand a fraction 1/b as the quantity formed by 1 part when a whole is partitioned into b equal parts; understand a fraction a/b as the quantity formed by a parts of size 1/b. Lesson Time: 50 minutes This 20-minute activity introduces students in Grades 3-5 to fractions

Equivalent Fractions

Standards CCSS.MATH.CONTENT.3.NF.A.2Understand a fraction as a number on the number line; represent fractions on a number line diagram. CCSS.MATH.CONTENT.3.NF.A.3.BRecognize and generate simple equivalent fractions, e.g., 1/2 = 2/4, 4/6 = 2/3. Explain why the fractions are equivalent, e.g., by using a visual fraction model. Lesson Time 30 minutes¬† Technology Required Device with web-browser–Chromebook, laptop, or

Video: Visualizing the Exact Fish Problem

Standards Apply and extend previous understandings of multiplication and division. CCSS.MATH.CONTENT.5.NF.B.3Interpret a fraction as division of the numerator by the denominator (a/b = a √∑ b). Solve word problems involving division of whole numbers leading to answers in the form of fractions or mixed numbers, e.g., by using visual fraction models or equations to represent the problem.  Visualizing the

One-half is one of two equal parts

Video: What is Half?

One half means it’s fair Who doesn’t want life to be fair? Learning fractions? Start with the most basic – dividing a whole into two equal parts. Equal is the key point emphasized here. It’s not enough to be in two parts, you need two equal parts. Fractions are more than pizza I like this

Video: When is a Fraction the Same as One?

When first learning fractions, I’ve found most students benefit from lots and lots of examples. It’s fine to teach rules and procedures, which I do, but I also try to show that rule applied in many different contexts. Watch this video for many examples of how N/N = 1 . Whether it is one trip,

Video: Math Terms

Knowing your math terms is important. Students asked to find the quotient may not get the right answer not because of an inability to divide 28 by 4 but rather because they don’t know what the word ‘quotient’ means. This video goes over the terms for addition, subtraction and multiplication. This video is featured in

Build a Model

Standard There’s more than one way to solve a problem, which is why we have a whole series of videos teaching problem-solving. Lesson One problem-solving strategy: build a model A model can be visual, as shown in this video. There’s also nothing wrong with a physical model, say, actually putting a dozen books in a
