## Mathematics

### FRACTIONS

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.

### DIVISION

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.
• Dividing 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.
• Build Your Own Division Problem – This lesson plan will build upon the introduction to division with 3-digit dividends from the “Dividing 3-Digit Dividends” lesson. Students will be able to continue practicing dividing 3-digit dividends by 1-digit divisors through a short review, activity where students build their own division problems, and game play.
• Fill in the Blank: 3 Digit Dividends – This lesson plan will have students reinforce the previously presented concept of long division of 3 digit dividends by 1 digit divisors (Dividing 3-Digit Dividends and Build Your Own Division Problem) through a short review, an animated video, a fill in the blank division word problem activity, and game play.
• Breaking down division with remainders – This lesson plan will explore how students interpret remainders in the context of a problem. They will learn how to divide and have a number leftover. Students will be using the concept of division and remainders.

### ESTIMATION

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.

### PROBLEM-SOLVING STRATEGIES

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.

## 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.

• Introducing Idioms – This lesson plan helps students recognize and understand idioms and what they are through different examples.
• Animal Idioms – This idioms lesson for Grades 3-4 begins with a presentation, popular song about idioms, a list of animal idioms, two video games, and an idioms matching activity. Also enclosed is a book list for Grades 1-4 about idioms.

CCSS.ELA-LITERACY.RI.4.1 Refer to details and examples in a text when explaining what the text says explicitly and when drawing inferences from the text.

• Cattails – Students will listen to or read a slide presentation. They will read an informational passage on cattails, write a summary and add new vocabulary words to their personal dictionary. The lesson ends with playing a game that teaches how medicinal herbs were used by indigenous people.
• Scrambled States: Ag in Language Arts – Teachers read The Scrambled States of America book, or have students read book or watch video. Students select a state from National Ag in the Classroom site and take notes on their state, including new vocabulary. Students read a book related to their state – link to a list is provided. Students complete a notes page and then use this page to write an informational essay.

CCSS.ELA-LITERACY.W.4.2 Write informative/explanatory texts to examine a topic and convey ideas and information clearly.

• Scrambled States: Ag in Language Arts – Teachers read The Scrambled States of America book, or have students read book or watch video. Students select a state from National Ag in the Classroom site and take notes on their state, including new vocabulary. Students read a book related to their state – link to a list is provided. Students complete a notes page and then use this page to write an informational essay.

CCSS.ELA-LITERACY.W.4.3 – Write narratives to develop real or imagined experiences or events using effective technique, descriptive details, and clear event sequences.
