Announcing Bridges in Mathematics Third Edition!

See what’s new in the curriculum!

Second graders add a new marker to the Calendar Grid for each day of the month. Students delve into important mathematics as they identify patterns that emerge in the markers over time. Each month also features a collection of data that students gather by taking measurements and conducting surveys. Students also build, sketch, and record arrays to match the day’s date as a way to explore addition and subtraction, as well as odd and even numbers.

Many days also feature an activity or game for strengthening students’ counting skills and computational fluency. These games and activities often incorporate visual models like ten-frames, double ten-frames, number lines, and number grids.
