K-5 Mathematics

Trimester 1

Concepts and Content

 Tri. 1 Areas of Focus Number and Operation: relationships among whole numbers, effects of addition on whole numbers, addition strategies and algorithms Measurement: Money Tri. 1 Resources Houghton Mifflin Harcourt Math Expressions Heinemann Contexts for Learning Mathematics Tri. 1 Materials 120 Number Chart Math Number Path Red/Yellow color counters Math Journal Math Mountain Cards Secret Code Cards Count on Cards Make a Ten Cards Ten Frames Coins Dice
Students will be able to demonstrate fluency with addition facts to 12.

Students will explore patterns and develop fluency in skip counting by 2s, 5s and 10s to 100.

Students will be able to name and understand the value of money; penny, nickel, and dime.

Students will use the four phases of problem solving; understand, plan, carry out and look back.

Students will use mental computation to add single digit numbers when written vertically and horizontally.

Students will be able to use the following addition strategies: count on, doubles, communativity of addition, and make ten.

Students will be able to communicate about mathematical thinking through written and oral language.

Help at Home

• Read the Family Letters that will come home at the beginning of each unit.
• Play number games: i.e. roll two or three dice and find their sum.
• Play board or card games with your child.
• Work with your child on mental calculations.
• Embrace multiple strategies.
• Encourage flexible thinking.

Trimester 2

Concepts and Content

 Tri. 2 Areas of Focus Number and Operation: addition, subtraction Measurement: time, money Tri. 2 Resources Houghton Mifflin Harcourt Math Expression Heinemann Contexts for Learning Mathematics Tri. 2 Materials 120 Number Chart Math Number Path Red/Yellow color counters Math Journal Secret Code Cards Count on Cards Make a Ten Cards Ten Frames Coins Analog and Digital Clocks Calendars Meter Stick Connecting Cubes

Students will see the relationship between addition and subtraction. They will use various strategies including but not limited to:

• Counting on
• Counting up to 10
• Doubles (An addition fact in which both numbers being added are the same.  For example, 5 + 5 = 10; 2 + 2 =4 are double facts.)
• Combinations of 10
• Subtraction as the inverse of addition

Students will be able to demonstrate fluency with addition fact to 20 and subtraction facts to 12.

Students will use horizontal and vertical notation for addition and subtraction.

Students will become familiar with the structure and patterns of our number systems.

Students will work with 100 and combinations of numbers that equal 100.

Students will be able to use the ‘number string’ concept.

Help at Home

• Work with your child in their acquisition of addition and subtraction facts.
• Practice mental computation.
• Find items sold in groups and ask your child to determine how many there would be in multiple sets or packages (e.g. soda cans, yogurt, batteries, etc.).
• Practice combinations of 100 using mental calculations, and horizontal equations. Discuss strategies taught in class.
• Tell addition and subtraction number stories. Have your child solve the problems using various household objects and then record the answers in number models. Remember to give a context for the numbers, such as coins, animals and so on.

Trimester 3

Concepts and Content

 Tri. 3 Areas of Focus Number and Operation: addition, subtraction Measurement: metric, non-standard and standard units Statistics: tables and graphs Tri. 3 Resources Houghton Mifflin Harcourt Math Expression Tri. 3 Materials 1-240 Number Chart Math Number Path Math Journal Secret Code Cards Count on Cards Make a Ten Cards Ten Frames Coins Analog Clocks Meter stick Number Cubes Ruler Base-Ten Manipulatives

Students will demonstrate fluency with addition and subtraction facts to 20.

Students will demonstrate an understanding of relative magnitude and position of numbers from
1 – 1000.

Students will demonstrate an understanding of the base ten number system using 1’s, 10’s, and 100’s up to 1000.

Students will represent a problem and its solution by using an efficient strategy.

Students will use mental computation to solve problems.

Students will subtract multi-digit numbers from multi-digit numbers with and without regrouping.

Students will use nonstandard units to develop an understanding of measurement. Students will use standard units of measure such as:

• Inches, feet, yards
• Centimeters, decimeters, meters

Help at Home

• Continue to work with your child in their acquisition of addition and subtraction facts.
• Build two and three digit numbers. Have your child identify the numbers and sequence them from smallest to largest discussing their relationship to one another.
• Play board or card games with your child.
• Estimate and measure distances at home.
• Include your child when using measuring at home in sewing, building and cooking.
• Go on a Scavenger Hunt. Use estimation skills to find objects of certain measurements.
• Measure how far you can jump from a standing position. Do this 5 times. How long was the longest jump? How long was the shortest jump? Measure 5 jumps for another member of your family.
