Scope and Sequence

Unit 1 – Addition Facts
This unit includes a review of basic addition and goes on to discuss word problems, counting on, doubles and near doubles, making a ten and adding a zero, changing the order of addends, number patterns, and adding three numbers. Math fact practice problems are provided.

Unit 2 – Subtraction Facts
This unit provides a review of basic subtraction, then discusses word problems, counting back, completing fact families, using addition to find differences, and identifying missing addends.

Unit 3 – Place Value I
This unit explains what place value is, the place value of ones and tens, the expanded form of numbers, number words to 100, and how to model numbers in different ways.

Unit 4 – Compare & Order Numbers/Number Concepts
This unit discusses ordinal numbers, comparing numbers with greater than, less than, and equals symbols, ordering numbers, rounding to the nearest ten, odd and even numbers, number patterns on hundreds charts, and skip counting by ten from any number.

Unit 5 – Two-digit Addition I
This unit covers adding a multiple of ten, regrouping when adding, and modeling, recording, and practicing two-digit addition.

Unit 6 – Two-digit Addition II
This unit reviews and provides practice for adding two-digit numbers, and discusses rewriting two-digit addition, adding tens (mental math), estimating sums, and using a table.

Unit 7 – Two-digit Subtraction I
This unit covers subtracting a multiple of ten, regrouping when subtracting, and modeling, recording, and practicing two-digit subtraction.

Unit 8 – Two-digit Subtraction II
This unit reviews and provides practice for subtracting two-digit numbers, and discusses rewriting two-digit subtraction, subtracting tens (mental math), checking subtraction using addition, estimating differences, and solving real world situations. It provides additional practice for two-digit addition and subtraction.

Unit 9 – Collect and Graph Data
This unit explains how to take a survey and how to use bar graphs, pictographs, and line plots. It also describes how to locate points on grids.

Unit 10 – Exploring Probability
This unit explores certain or impossible, more likely, less likely, or equally likely events, and possible outcomes.

Unit 11 – Money I
This unit explains the value of dimes, nickels, pennies, half dollars, and quarters. It provides practice counting money and using coins to show the same value with different combinations.

Unit 12 – Money II
This unit covers comparing amounts of money, using money to buy objects, adding and subtracting money, making change, and the dollar.

Unit 13 – Time
This unit discusses minutes and hours, telling time to fifteen minutes and to five minutes, recognizing minutes before the hour, using a.m. and p.m., and determining how much time has passed. Also covered are days, weeks, months, years, and calendars.

Unit 14 – Geometric Solids
This unit covers identifying solid figures; which solid figures slide and roll; faces, edges, and vertices of solid figures; and solid and plane figures.

Unit 15 – Plane Figures and Transformations
This unit identifies plane figures and their slides and vertices. It further discusses combining and separating plane figures, slides, flips, and turns, congruent plane figures, and symmetry.

Unit 16 – Exploring Patterns
This unit discusses identifying, extending, and creating patterns, finding a pattern’s missing piece, patterns that grow, and extending growing patterns.

Unit 17 – Exploring Length
This unit explores inches, feet, yards, centimeters, meters, and estimating length in both the US Customary and the Metric Systems. It also discusses finding perimeter and area, the difference between a shorter and a longer length, and word problems having to do with length.

Unit 18 – Measure Weight, Mass, Capacity, and Temperature
This unit discusses using the correct tool for measuring, as well as measuring in ounces, pounds, grams and kilograms, cups, pints, quarts, gallons, liters, degrees Fahrenheit, and degrees Celsius.

Unit 19 – Exploring Fractions
This lesson covers fractions that describe just one of the equal parts of a whole, comparing these “one-equal-part” fractions, fractions that describe multiple equal parts of a whole, fractions that describe one whole, and fractions that describe parts of a group.

Unit 20 – Understanding Place Value
This unit covers ones, tens, and hundreds, identifying place value, the expanded form of three-digit numbers, and modeling numbers in different ways.

Unit 21 – Compare and Order Numbers II
This unit covers comparing and ordering 3-digit numbers, and counting by fives and tens.

Unit 22 – 3-Digit Addition
This unit covers adding a multiple of 100, regrouping ones and tens in 3-digit addition, estimating 3-digit sums, and practicing 3-digit addition.

Unit 23 – 3-Digit Subtraction
This unit covers subtracting a multiple of 100, regrouping tens and hundreds in 3-digit subtraction, estimating 3-digit differences, and practicing 3-digit addition and subtraction.

Unit 24 – Multiplication and Division
This unit introduces multiplication and division, including skip-counting to find a total, the relationship between addition and multiplication, multiplying using an array, the commutative property of multiplication.
