Course: 4th Grade Math
Course Description
Units and Lessons
Time
Resources: 60 This unit is great for reteaching time. Lessons are broken down into telling time by the hours, half hour, quarter hour, 5 minute, and 1 minute intervals. The unit also covers elapsed time in both word problems and calendar format and introduces the concept of am and pm to students. Standards covered: 4.M.3. Identify time to the minute on analog and digital clocks using a.m. and p.m. Compute elapsed time using a clock (e.g., hours and minutes since …) and using a calendar (e.g., days since …).

Using Variables
Resources: 31 This unit covers using variables in equations and inequalities. The unit covers using variables in problems that involve addition, subtraction, multiplication, and division. One lesson is devoted to using signal words to determine the operation. The final lesson focuses on inequalities with three variables. Standards covered: 4.PRA.2. Use letters and other symbols (e.g., L, x) as variables in expressions and in equations or inequalities (mathematical sentences that use =, <, and >).

Rounding
Resources: 37 This unit includes key terms for rounding, rounding from the tens to the hundred thousands place, and using rounding to estimate a sum or product. The lessons are broken down by place value to assist with reteaching rounding to a specific value. Standards Covered: 4.NSON.3. Round whole numbers to 100,000 to the nearest 10, 100, 1,000, 10,000, and 100,000. 4.NSOE.29. Estimate the answers to calculations involving addition, subtraction, or multiplication; know when approximation or a rounded solution is appropriate and use it to check the reasonableness of answers.

Estimation
Resources: 33 This unit includes the explicit teaching of three strategies for estimation: rounding, frontend rounding, and regrouping. It also includes estimating techniques and computations for three digits and values to $1,000. Finally, the unit closes with students judging the reasonableness of their answers. Standards covered: 4.NSOE.28. Estimate and compute the sum or difference of whole numbers and positive decimals to two places; 4.NSOE.29. Estimate the answers to calculations involving addition, subtraction, or multiplication; know when approximation or a rounded solution is appropriate and use it to check the reasonableness of answers.; 4.NSOE.30. Select and use a variety of strategies (e.g., frontend, rounding, and regrouping) to estimate quantities, measures, and the results of wholenumber computations up to threedigit whole numbers and amounts of money to $1,000 and to judge the reasonableness of answers.

Understanding Fractions
Resources: 65 This unit focuses on the student's gaining an understanding that fractions are parts of a whole. It moves to understanding fractional values on a number line. The unit quickly touches on fractional sums and differences and equivalent fractions. The students learn about the relationship between fractions, percents, and decimals and learn the rules for converting between the values using a calculator. Standards covered: 4.NSOF.9. Demonstrate an understanding of fractions as parts of unit wholes, as parts of a collection, and as locations on a number line. 4.NSOF.10. Know the relationships among halves, fourths, and eighths and among thirds, sixths, and twelfths; compare and order such fractions. 4.NSOF.11. Recognize, name, and generate equivalent forms of common decimals (0.5, 0.25, 0.2, 0.1) and fractions (halves, quarters, fifths, and tenths) and explain why they are equivalent.

Models, Tables, and Graphs
Resources: 68 This unit covers 3 major standards (listed below). The unit begins with a lesson on relevant and irrelevant information in word problem to assist the students with critical thinking. The unit then covers patterns, calculating unit cost, total cost, and a new total cost, input/output tables with both single and multi step equations, calculating total distance when using a scale, proportional relationship problems which include balance scale problems. Standards covered: 4.PRA.3. Use pictures, models, tables, charts, graphs, words, number sentences, and mathematical notations to inter pret mathematical relationships. 4.PRA.4. Solve problems involving proportional relationships, including unit pricing. 4.PRA.5. Determine how change in one variable relates to a change in a second variable (e.g., inputoutput tables).

Multiplication and Division
Resources: 22 This unit is intended for students struggling with multiplication and division. The short unit includes lessons that explain conceptual foundations of multiplication, or strategies to assist struggling learners, such as repeated addition and using models. The unit then quickly explains the relationship between division and multiplication. Standards covered: 4.NSOC.17. Select, use, and explain various meanings and models of multiplication and division of whole numbers. Understand and use the inverse relationship between the two operations. 4.NSOC.21. Multiply fractions by whole numbers, using repeated addition and area rectangular models

Addition and Subtraction
Resources: 19 This unit is designed for reteaching students that are struggling with the computation of addition and subtraction of 4 and 5 digit. It explains the column addition strategy and the trade first method of subtraction. Standards covered: 4.NSOC.14. Demonstrate an understanding of and the ability to use conventional algorithms for the addition and subtraction of multidigit whole numbers. 4.NSOC.15. Add and subtract up to fivedigit numbers accurately and efficiently.
