CCSS.MATH.CONTENT.3.NF.A.1 – Understand a fraction 1/b as the quantity formed by 1 part when a whole is partitioned into b equal parts

  • Introducing Fractions – The student will learn the definition of fraction, parts of fractions and how fractions have been used in past and present.

CCSS.MATH.CONTENT.4.NF.B.3.A – Understand addition and subtraction of fractions as joining and separating parts referring to the same whole.

CCSS.MATH.CONTENT.4.NF.B.3.D – Solve word problems involving addition and subtraction of fractions referring to the same whole and having like denominators, e.g., by using visual fraction models and equations to represent the problem.

  • Subtracting Fractions: Like denominators – Students will learn how to solve multi–step word problems using addition and subtraction of fractions with like (common) denominators.
  • When a fraction equals 1 – This lesson plan will build upon the already introduced concepts and key terms of fractions in our “Introducing Fractions” lesson plan. Students will learn that a fraction N/N =1 and be able to solve problems with fractions equal to 1 in various contexts, including number lines, time and pizza.

CCSS.MATH.CONTENT.5.NF.B.4 – Apply and extend previous understandings of multiplication to multiply a fraction or whole number by a fraction.

  • Multiplying fractions with like denominators – This lesson plan will explore how students can take what they already know about adding fractions with like denominators in order to grasp multiplying fractions with like denominators.


CCSS.MATH.Content.4.NBT.B.6– Find whole-number quotients and remainders with up to four-digit dividends and one-digit divisors, using strategies based on place value, the properties of operations, and/or the relationship between multiplication and division. Illustrate and explain the calculation by using equations, rectangular arrays, and/or area models.

  • Introducing Division – This lesson plan introduces the concepts and vocabulary of division and provides students the opportunities to practice both recognition and recall of division facts.
  • Division and English/ Language Arts – This is a fun lesson where students practice division, combined with Ojibwe history and then complete a creative writing assignment.
  • 3-digit Dividends – This lesson will build upon the already introduced concepts and vocabulary of division in our “Introducing Division” lesson. Students will learn and be able to practice dividing 3 digit dividends by 1 digit divisors through a short review, activity, and game play.  


CCSS.MATH.CONTENT.4.NBT.B.5 – Multiply a whole number of up to four digits by a one-digit whole number, and multiply two two-digit numbers, using strategies based on place value and the properties of operations.

CCSS.MATH.CONTENT.4.OA.A.3 – Solve multistep word problems posed with whole numbers and having whole-number answers using the four operation … Assess the reasonableness of answers using mental computation and estimation strategies including rounding.


CCSS.MATH.PRACTICE.MP4 Model with mathematics.
CCSS.MATH.PRACTICE.MP1 Make sense of problems and persevere in solving them.

  • In Problem-solving Two Ways , students learn about and practice the two strategies of building a model and visualization.
  • Problem-solving with Pigs teaches two more problem-solving strategies, using operations keywords and starting at the end to see what a problem is really asking. It is part of a cross-curricular lesson that includes learning about how pigs are raised.

Also, search the mathematics video catalog for additional resources.

English/ Language Arts

CCSS.ELA-LITERACY.L.4.5.B – Recognize and explain the meaning of common idioms, adages, and proverbs.

CCSS.ELA-LITERACY.L.5.5.B – Recognize and explain the meaning of common idioms, adages, and proverbs.
