Grade 3 Math in New Brunswick
New Brunswick Grade 3 math covers a wide range of foundational topics that prepare students for more advanced math in later grades. Students explore number patterns, place value up to 1000, mental math strategies, early multiplication and division, fractions, measurement, geometry, and data collection. StudyPug provides video lessons and practice for every one of these topics, aligned to the New Brunswick curriculum.
Number Sense and Patterns
Grade 3 students learn to count by 3s, 4s, 5s, 10s, 25s, and 100s from any starting point. They compare and order numbers up to 1000 and use referents to estimate quantities. Place value is explored concretely and pictorially to help students understand the value of digits in any three-digit number. Students also describe, extend, and create patterns using manipulatives, diagrams, sounds, and actions.
Addition, Subtraction, Multiplication, and Division
Students apply mental math strategies for adding and subtracting two 2-digit numbers and use estimation to predict sums and differences. They practice multiplication up to 5×5 and learn division related to those multiplication facts. Key strategies include doubles, making 10, the commutative property, the property of zero, and thinking addition for subtraction. StudyPug breaks each strategy into short, clear video lessons so your child can master one concept at a time.
Fractions, Measurement, and Geometry
Grade 3 introduces fractions as part of a whole, with students comparing fractions with like denominators. In measurement, students work with non-standard and standard units of time, explore the relationship between seconds, minutes, hours, and days, and measure length, width, height, and mass using centimetres, metres, grams, and kilograms. They also calculate the perimeter of various shapes. In geometry, students describe 3-D objects by faces, edges, and vertices, and sort polygons by number of sides.
Data and Graphing
Students collect and organize data using tally marks, line plots, charts, and lists. They create and interpret bar graphs to answer questions and solve problems. StudyPug's practice problems help students apply these skills with confidence.
