Bridges is a research based, rigorous, comprehensive math curriculum aligned to the Common Core State Standards. This page, along with the Bridges Family Support page, will provide resources and information to families and students. I appreciate your involvement in your student's learning. Students should make their best attempt at the Home Connections homework. Please avoid any excess stress for your student and please circle any problems your student needs help with and send it to school the next day with a quick note. I will review the Home Connections and provide support and clarification.
Unit 1 - Addition and Subtraction Patterns
In Unit 1, students will review and strengthen their addition and subtraction skills learned in second grade. This includes a focus on addition and subtraction facts, the pattern of adding 10's, measuring, and problem solving. The first module (week) reviews addition strategies for facts to 20. The second module revisits subtraction strategies for facts to 20. Students are introduced to multi-digit addition on the open number line in module three and module four presents a collection of story problems and practice with multi-digit adding and subtracting. Below are some PDF documents that can be helpful in providing support for your student's Home Connections homework. Paper copies of these documents are also sent home throughout the unit.

Unit 2 - Introduction to Multiplication
In this unit, students are introduced to the concept of multiplication. Students work with a variety of models for multiplication including repeated addition, arrays, ratio tables, equal groups, and the number line. Students apply the associative, commutative, and distributive properties to develop efficient, reliable, and generalization strategies for multiplying. By the end of grade 3, students are expected to master facts through 10x10. Students will look at patterns and strategies on the multiplication table to build multiplication fact fluency in this unit. Fact fluency is not expected by the end of this unit, as it will be revisited in unit 5 and 7, as well as all throughout the year. Students will also solve story problems involving multiplication and multi-step story problems involving multiplication and addition/subtraction.

Unit 3 - Multi-Digit Addition & Subtraction and Rounding
Unit 3 reviews and extends students' thinking about place value, multi-digit addition and subtraction, and problem solving. Students will begin the unit by rounding 2 and 3 digit numbers to the nearest ten and the nearest 100. This skill is extended into problem solving, as students use rounding as a way to estimate and check the results of adding and subtracting multi-digit numbers. Along with reviewing and strengthening the strategies learned to add and subtract, students will focus on using the algorithm, or standard way of solving addition and subtraction with regrouping.
Games
*Practice rounding to the nearest 10 by matching a 2 digit number to its rounded pair.
*Choose the second game called "Addition by Splitting"
*Estimate sums by rounding and adding.

Unit 4 - Measurement and Fractions
This unit begins with measurement concepts and skills. Students tell time to the minute and solve elapsed time problems. Then the class discusses the need for measuring by reading a book about the biggest, tallest, and fastest animals in the world. At the end of the first module, students estimate, measure, and compare the masses of different objects. In the second module, students work with volume and solve measurement-related story problems. The third module introduces them to fractions, using several different models to build, compare, and investigate the relationships among unit and common fractions. A short project at the end of the unit brings it all together, as students measure lengths to fractions of an inch and display measurement data on line plots.
Games
*Students measure animals at the vet using centimeters and grams. Click the play button to begin the game.
*Students try to sink battleships by plotting fractions on a number line.

Unit 5 - Multiplication, Division, and Area
Unit 5 returns to the study of multiplication, especially as it relates to division. The focus of this unit is the relationship of multiplication and division being inverse or opposite operations, just like addition and subtraction. Students again build arrays, but use them to model and solve division as well as multiplication problems. Students work through realistic story problems to discover the two types of division - sharing and grouping. Students will also build fact fluency by working with multiplication and division fact families. Students will also explore the concept of area and how it relates to multiplication.
Games
Race against the computer or other students by clicking on the correct quotient in a series of division problems. Fun fact practice!
This website provides a teaching walk through for area and practice at three levels of difficulty.
Click on the figures that have a given area.
Click and drag a shape tool to create enclosures that are the correct area and/or perimeter for animals at the zoo.

Use this tool to create arrays up to 10 x 10 and demonstrate how they are related to multiplication.
This article explains how array models can be used to help students develop understanding of multiplication and division.
This teaching tool allows you to choose an object (example: soccer balls) to group in problems with or without remainders. View a story problem using the object: "Gordon has 14 balls to put into bags of two. How many bags will there be?" Click on "make a group" and see the item grouped.
This teaching tool allows you to choose an object (example: fish) to share in problems with or without remainders. View a story problem: "There are 30 fish to be shared equally amongst 6 tanks. How many fish in each tank?" Click on "share out" to distribute the objects.

Unit 6 - Geometry
In Unit 6, students will describe, classify, and make observations about two dimensional shapes. Students will build and make various polygons and quadrilaterals. Through making the shapes, students will discover their similarities and make comparisons. Quadrilaterals, are the major focus of third grade geometry. Students will analyze and classify squares, rectangles, parallelograms, rhombuses, and trapezoids. In order to do so, students will discover the concepts of parallel and perpendicular lines, acute, right, and obtuse angles, and line symmetry. Students measure and find the perimeter and area of various polygons. At the end of the unit, students apply what they know about shapes, area, and fractions.
Games
This PBS Kids game has students use area and perimeter to create airplane shapes on a geoboard that would have enough seats for the passengers.

Unit 7 - Extending Multiplication and Fractions
Unit 7 revisits and extends two of third grades key concepts, fractions and multiplication. This unit provides students opportunities to extend and review skills and concepts into work with larger numbers and bigger ideas. In extending multiplication, students will learn to multiply single digits by multiples of 10, how to multiply 1 digit by 2 digit numbers, and to apply the commutative, associative, and distributive properties of multiplication. Extending fractions will involve students will expand the idea of fractions on a number line, fractions of a set, and fractions of a whole using linear and area models.
Games
This game provides practice with single digit multiplication, 2 digit x 1 digit multiplication, and 3 digit/1 digit division with remainders.
Color blocks to represent a given fraction. Five levels from which to select. At the lowest level players shade in 1/2 of 4,6,8, or 10; at the highest level, shade in 1/3 or 2/3 of 6, 9, or 12.
