4th Grade Mathematics

In the 4th grade, students become more independent as problem solvers. The year starts with the introduction of more complex modeling with arrays for multiplication and division, laying the groundwork with a variety of algorithms and strategies for solving problems. Working both individually and in groups, students continue to develop their number sense through hands-on projects around measurement, games, word problems, and extrapolating data necessary for solving a problem. Explaining their thinking when solving a problem is at the heart of the Bridges in Mathematics program. In geometry, hands-on activities help teach area and volume in flat and three-dimensional shapes, and students move into two-dimensional sketching of the same concepts. Students also increase their mathematical vocabulary and their ability to articulate their thinking in solving problems through daily practice at school and at home.
