Course Outline

Unit 1: Read, Write, Count, and Compare Numbers

This unit focuses on counting, comparing, and ordering numbers. Students explore reading and writing whole numbers, which prepares them to later add and subtract numbers. The skill of skip counting by 2s, 5s, and 10s assist students in comparing and ordering numbers. Skip counting also serves as an important introduction to number patterns as a first step to learning algebraic concepts.

  • Numbers Through 50
  • Write Numerals Through 50
  • Count by 10s and 5s Through 50
  • Count by 2s Through 50

Unit 2: Time and Position

Students learn about the hour hand and how to tell time to the nearest hour. Then they learn about the minute hand and how to tell time to the nearest half hour. They learn to identify when it is exactly, a little before, or a little after the hour and the half hour, and to draw these scenarios on a clock. Then students relate time to events, and compare events by how long they take to complete and by the order in which they occur. Students learn to compare, arrange, and describe the position of objects using words such as up, down, behind, in front of, next to, to the left of,>/em> and to the right of.

  • Time to the Nearest Hour
  • Time to the Nearest Half Hour
  • About Time
  • Arrange and Describe Position
  • Use Direction Words

Unit 3: Introduction to Addition

The concept of part-part-whole is foundational to many topics in math from addition and subtraction to measurement and geometry. Students learn that the meaning of addition is putting together groups of objects, and that the order in which groups are added does not affect the sum. They use sketches, counting chips, and snap blocks to model addition problems, learning that addition is combining, or putting together, groups of objects. They are introduced to the plus sign (+) and the equals sign (=) and learn how to write number sentences using numbers, the plus sign, and the equals sign.

  • Model Addition
  • Add in any Order
  • The Plus Symbol
  • The Equals Symbol
  • Number Sentences: The Equals Symbol

Unit 4: Addition Facts for Sums Through 12

Students begin by learning different ways to add numbers to make 8, and what happens when adding 0. Students then learn the addition facts for sums through 8, and then sums through 12. They use online and offline flash cards and other activities to help them develop automatic recall, and they complete a chart to document their progress.

  • Facts Through 8
  • Sums Through 8

Students use online and offline flash cards and other materials and tools to help them develop automatic recall. They complete a chart to document their progress.

  • Facts Through 16
  • Sums Through 16
  • Facts Through 20
  • Sums Through 20

Unit 6: Addition Strategies

Students learn to find one more than and ten more than another number. They practice finding one more and ten more using hundred charts and number lines. This leads to learning how to add two numbers by counting on. Students use counting chips and number lines to assist with counting on to add. They learn that counting on from the greater number is easier than counting on from the lesser number. Students are introduced to the associative property, learning that they can group three numbers in different ways to make it easier to find their sum. Finally, students use the various addition strategies they have learned—counting on, using doubles, using memorized facts and similar facts, and grouping to solve addition problems with sums through 30.

  • One More, 10 More
  • Count On to Add
  • Different Ways to Add
  • Grouping to Add
  • Grouping Addends

Unit 7: Addition Number Sentences

Students identify and practice showing numbers in various ways—with models, sketches, and with addition expressions. They then represent equivalent forms of the same number in multiple ways. Students use a balance to help identify equivalent forms of a number, including two addition expressions that are equal. Then they find a missing number in an addition sentence using the balance. They identify missing sums and missing addends, using the balance and snap cubes as tools. They learn that you can add two numbers in any order and the sum will not change. They explore this property with balance snap cubes, then use this knowledge to find missing addends in number sentences with addition expressions on each side.

  • Different Forms of Numbers
  • Ways to Show Numbers
  • Missing Numbers in Addition
  • Missing Numbers in Addition Sentences

Unit 8: Introduction to Subtraction

Students learn that subtraction means to take away, and they demonstrate the meaning of subtraction by taking away objects. They learn that when they subtract, the number that is left is the difference. They learn the meaning of the minus symbol (-) and review the meaning of the equals symbol (=) so they can read and write subtraction sentences. Students explore the relationship between addition and subtraction, learning that they are opposite operations. They demonstrate the opposite operations with objects and drawings. They learn that subtraction is not commutative, and that subtracting zero from a given number results in a difference of the original number. Students then learn about using subtraction in comparing numbers, which allows them to find how much greater or lesser a number is than another number. They use pairing, modeling, and drawings to compare numbers.

  • Understand Subtraction
  • The Minus Symbol
  • Equal Expressions
  • More Equal Expressions
  • Put Together, Take Away
  • Order and Zero in Subtraction

They use base-10 blocks, models, or sketches to solve addition and subtraction story problems. Students work with the concept of parts and total, how to recognize a problem in which amounts are combined, and that they can use subtraction to solve a problem in which one part and the total are given and the other part is missing.
