COURSE OUTLINE

Unit 1: Shapes and Sorting

This unit focuses on describing, sorting, and classifying objects according to attributes or features. Students investigate the attributes of geometric shapes, such as circles, triangles, squares, and rectangles. They also use everyday objects, such as beads, stuffed animals, or types of fruit to improve their skills.

• Identify Plane Figures
• Circle, Triangle, Square, Rectangle
• Compare Shapes
• Compare Colors
• Compare Sizes
• Sizes, Shapes, and Colors
• Sort by Color
• Sort by Shape
• Sort by Size
• Sorting Different Ways

Unit 2: Shapes and Patterns

Students identify which object from a group does not belong according to the color, shape, or size of the objects. Students also learn what a pattern and a pattern core are and view different pattern types. Students begin using the letters A, B, and C to describe pattern rules AB, ABB, AAAB, AAB, ABB, ABC, and ABCC. Students identify and extend these patterns with attribute blocks and other objects.

• Which Object Is Different?
• AB and ABB Patterns
• AAAB and AAB Patterns
• ABCC and ABC Patterns

Unit 3: Numbers Through 5 and Plane Figures

Students begin by counting and grouping objects into groups of up to five, and then learn to write the numerals 1 through 5. They review triangles, squares, rectangles, and circles; learn to identify and count sides and corners—and find out that circles do not have sides or corners.

• Count Through 5
• Count and Show 0 Through 5
• Write Numerals Through 5
• Sides of a Shape
• Corners of a Shape
• Sides and Corners of Shapes

Unit 4: Numbers Through 10

Students begin by hearing the counting sequence of numbers from 1 through 10, and then they count aloud on their own. They represent quantities through 10 by using objects and drawings. Students then move to counting sets of 10 or fewer objects, learning that they can count the objects in any order as long as they count each item exactly one time. Students read the numbers 1 through 10 to prepare them for writing the numbers. By watching a virtual pencil, and practicing with pencil and paper, they learn to form the numbers themselves. Students learn to compare and order groups of objects, learning that numbers with greater values describe groups with more objects than numbers with lesser values. They move to comparing and ordering numbers that describe groups of objects.

• Count Through 10
• Show an Amount Through 10
• Represent Amounts
• Count Aloud Through 10
• Show Amounts in Different Ways
• Write Numerals 1 Through 10
• More, Fewer, and Equal
• Compare and Order Groups
• Describe and Order Groups by Number
• Write Numbers to Describe Groups

Unit 5: Calendar and Time

This unit is a review of calendars and time lessons taught throughout the first quarter. In the online Calendar/Time activities, students have learned about calendar concepts such as the names and numbers of days in a week; the notion of yesterday, today, and tomorrow; how to find a specific date on a calendar; and how many months are in a year. Students have also learned about concepts of time by studying the hours and minutes on a clock; parts of the day such as morning, afternoon, and evening; and the typical times in a day when certain activities occur.

• Understanding Concepts of Time

Unit 6: Data and Graphs

Students learn how to compare groups of objects to determine which group has more or fewer objects, and that greater numbers are used to describe groups with more objects. Students learn to collect data and represent that data with objects, pictures, and picture graphs. They pose questions, collect data, record the results, compare, and answer questions. Students also learn to compare and answer questions about data in graphs that they have not prepared themselves.

• Collect Data and Pose Questions
• Ways to Show Data
• Compare Data in a Picture Graph
• Interpret Picture Graphs
• Answer Data Questions
• Analyze Data in Picture Graphs

Unit 7: Numbers Through 20

Students begin by counting groups of up to 20 objects, learning that they can count in any order as long as each item is counted once. They use models, drawings, and finally numerals to represent groups of up to 20 objects. Students then compare groups having 20 or fewer objects to determine which has more, fewer, the most, or the fewest objects. They compare numbers from 1 through 20 to determine which is more or greater, and which is lesser or fewer. They learn to write the numerals from 1 through 20.

• Count Aloud Through 20
• Represent an Amount Through 20
• Count Through 20
• Show Amounts Through 20
• Compare Sets Through 20
• Write Numerals Through 20
• Compare Numbers and Sets Through 20
• Write Numerals from 1 Through 20

Unit 8: Introduction to Addition

Students learn the meaning of addition by combining two groups of objects to find the total. By experimenting with groups of objects, they learn that changing the order in which the numbers are added does not change the sum. Students then learn to add with sums through 20 by using number lines, models, and sketches. They also learn to add by counting on by 1 and by 2 from a number.

• Combine to Add
• Count On to Add
• Count On
• Add with Models
• Use Sketches to Add

Unit 9: Problem Solving With Addition

Students use concrete objects to solve addition story problems that involve combining groups, and explain how they are solving them. They move on to problems in which one of the groups is unknown (missing addend problems), and to checking answers to addition word problems. Students also learn how to estimate to find a sum.

• Addition Problem Solving
• Addition Story Problems
• Explain Addition Solutions
• Combine to Find Totals
• Recognize Combine Problems
• Missing Parts Problems
• Estimate Sums Through 20
• Check the Accuracy of Calculations

Unit 10: Introduction to Subtraction

In this unit, students are introduced to subtraction as taking away objects from a group of objects. They learn to take away objects and to tell how many are left, and then use sketches and countable objects to model subtraction problems and story problems. Students learn that through subtraction, they can also find out the amount of a mystery addend in an addition problem.

Students learn to apply their knowledge by using benchmarks of 5, 10, 15, and 20 to make reasonable estimates for solutions to subtraction problems. They learn that counting principles and numbers can be used to solve addition and subtraction problems and use models or sketches to check the accuracy of their solutions to subtraction word problems.

Unit 11: Problem Solving with Subtraction

Students learn to recognize and solve subtraction story problems by using concrete objects and sketches. They create their own story problems, and then solve those problems using models or sketches. They apply that knowledge to make reasonable estimates for solutions and check the accuracy of subtraction calculations.

• Model Subtraction Stories
• Sketch Subtraction Stories
• Take-Away Stories
• Compare Take-Away and Combine
• Recognize and Solve Problems

Unit 13: Comparison Subtraction: Story Problems

In this unit, students learn to use concrete objects to explain how to solve addition and subtraction problems involving numbers up to 10. Students also learn to recognize and solve word problems involving numbers up to 10 in which two quantities are compared by the use of addition or subtraction. Students then make estimates for solutions to subtraction problems and check the accuracy of those solutions.

Unit 16: Numbers Through 30

Students extend their counting ability to be able to count up through 30 objects in a group. They learn to represent amounts through 30 with objects and with sketches, and to compare groups of objects. Students determine which of two groups has more or fewer objects. They then can tell which of three groups has the fewest or the most objects. Finally, students learn to write numbers from 1 through 30.

They learn to identify these figures and to recognize them in everyday objects such as boxes and marbles. They compare the attributes of the various solids, such as the number of corners, the roundness, the color, or the size. Students identify which solid in a set of solids does not belong according to color, size, or shape.
