Bridges in Mathematics Family Support: Grade 4
In grade 4 math, your child will:
- Understand factors and multiples, e.g., 1, 2, 4, 5, 10, and 20 are all factors of 20, and 20 is a multiple of each of those numbers
- Understand that a prime number has only 2 factors—1 and itself, while a composite number has more than 2 factors
- Multiply multi-digit numbers using strategies based on place value and properties of operations
- Divide 2-digit numbers by 1-digit numbers using strategies based on place value and the relationship between multiplication and division
- Read, write, and compare multi-digit numbers and round multi-digit numbers to any place
- Add and subtract multi-digit numbers accurately and efficiently
- Recognize and generate equivalent fractions
- Compare two fractions with different numerators and denominators
- Add and subtract fractions and mixed numbers with like denominators
- Multiply a fraction by a whole number
- Write fractions with denominators of 10 or 100 in decimal notation
- Compare decimal numbers with digits to the hundredths place
- Know the relative sizes of measurement units within one system of units, including metric length, metric mass, customary weight, metric volume, and time
- Use formulas for area and perimeter of a rectangle to solve problems
- Measure and sketch angles with a protractor
- Classify 2-D shapes
- Identify and draw lines of symmetry
Bridges Unit Overviews
The following selection of games and activities will help your child practice these skills at home.
Times Square This game provides practice with multiplication facts as players race to be the first to get 4 products in a row on the game board. Use "guest pass" to enter game list and play against the computer.
Factor Dazzle Players score points for finding all the factors of target numbers set by their opponents. Use "guest pass" to enter game list and play against the computer.
MathTappers: Multiples App compatible with iPhone, iPod touch, and iPad for math practice on the go. This is a simple, free game designed to help learners make sense of multiplication and division using visual models.
Drag Race Division Race to answer basic division problems. Students can race one another or play against the computer.
Dig It Players take turns digging in a field loaded with precious stones. The object is to collect as much dirt and as many stones as possible. Players tell the shovel where to dig by using a set of numbers to make a fraction–including improper fractions–and then locating that fraction on a number line that runs across the field. The more accurately they locate the fraction, the better their score. Students may need some help to get started. Use "guest pass" to enter game list and play against the computer.
Fraction Feud Players use number "cards" to create fractions that are larger (or smaller) than their opponents' in a series of mock jousts. See the "fraction bar chart" to figure out how big a fraction is in relation to an opponent's. Use "guest pass" to enter game list and play against the computer.
Drop Zone Players add fractions that will total 1 as they race to win 5 points in this action-packed game. Develops fraction sense, estimation, and skill at adding fractions with like and unlike denominators. Use "guest pass" to enter game list and play against the computer.
Equivalent Fraction Bingo Match the numerical fraction to its equivalent visual model.
Fraction Fling Match fraction to the visual model and hit the fraction to answer the question. Players can choose to use mixed fractions while playing.
MathTappers: Estimate Fractions In this free app for iPhone, iPod touch, and iPad, students relate fractions (symbols and pictures) to the nearest half. Then they use fraction estimates in addition and subtraction problems. Excellent game to use while on the go.
Pecking Order Arrange fractions and decimals from least to greatest on a number line.
neXtu Players place shapes on a tessellating game board, collecting points and capturing opponent's pieces. Math concepts include: greater than, less than, tessellations, and symmetry.
Alien Angles Slide a bar to position a ray to estimate different angles in order to rescue lost space aliens.
