Overview of Math Units
- Our district uses the Math Expressions Common Core series at the elementary level for researched based math instruction that focuses on problem solving and real life applications. The unit that the students are currently studying is highlighted in red!
Math Units 1 and 2 - Multiplication/Division
Students begin the year with multiplication and division! They study the following concepts/skills in these units.
ªUse multiplication and division within 100 to solve word problems
•Determine the unknown number in a multiplication or division equation
•Memorize multiplication and division to 100
•Apply the Associative, Commutative and Distributive Property of Multiplication.
•Solve word problems using rounding and estimation.
Multiplication/Division Practice
Students are using multiplication.com to monitor their progress with fluency of the multiplication and division facts. The goal is to have these memorized by the end of the year. Students are earning an ice cream sundae party by passing timed tests with 100% accuracy. We have stressed with the students that it will take daily effort, but being fluent with the facts will help them tremendously in fourth grade and beyond! Please practice at home with your child. Students are welcome to take the multiplication.com tests at home! If your child scores 100% within two minutes, please just email or send a note to school saying which test they passed and whether it was multiplication or division. The link for multiplication.com is on our resource page along with links for a variety of multiplication and division online games and activities. Also provided are links for a variety of games to review addition/subtraction facts. Thank you so much for helping your child at home!
Unit 3 - Multi-Digit Addition and Subtraction
In this unit your child participates in activities that help him/her understand place value, rounding, and addition/subtraction of 3-digit numbers.
•Place Value - Students learn to represent numbers with drawings. The drawings are also used to help students understand regrouping in addition and subtraction.
•Rounding - Students learn to estimate sums and differences by rounding numbers. Estimation provides students with methods to validate their answers.
•Addition/Subtraction - Students review many different strategies to regroup or ungroup when adding and subtracting multi-digit numbers. Students gain an understanding of the relationship between addition and subtraction and see them as inverse operations.
•The students apply their knowledge of concepts and skills to problem solving.
Units 4 - Explore Fractions, Time, and Data
Learning goals will focus on the following concepts:
•Fractions - Students study fraction concepts, beginning with unit fractions and what they represent. They model fractions in various ways as they compare and find equivalent fractions. Visual models and real world situations are used throughout the unit to illustrate important fraction concepts.
•Length, - Students measure to the nearest 1/2 and 1/4 inch. and learn different ways to organize their data.
•Telling time - This includes time before and after the hour, time to the nearest minute, and elapsed time.
•Pictographs, Bar Graphs and Line Plots - This includes drawing scaled graphs and solving comparison problems using data.
Unit 5 - Measurement (Area and Perimeter) and More Fractions
Students find the perimeter and area of various shapes and explore the relationship between them. They also expand their study of fractions to fractions on a number line and using equations to compare and create equivalent fractions.
Unit 6 - Write Equations to Solve Multi-Step Word Problems
In this unit, students study problem solving and problem types. They use their knowledge of carrying out operations, inverse operations, reading problems, and properties of operations to develop proficiency in solving two step problems. Visual models and real world situations are used throughout the unit to illustrate important problem solving concepts.
Unit 7 - Measurement (Capacity, Weight, and Mass) and Polygons
Students explore customary and metric units of liquid volume, and the weight and mass of objects. They also analyze and classify triangles and quadrilaterals according to their attributes
