Houghton Mifflin's "Math Expressions: Grade 2" includes problems involving counting to 10, word problems, coinage, subtraction, basic multiplication, linear measurements, shapes, time, geometry, three-dimensional spaces and metric measurements. The school year is split into 14 units that introduce basic concepts of mathematics and builds on each concept as the year progresses.Continue Reading
The school year begins with a recap of counting to 10 using pennies. Concepts like a "partner house" show similar sums of different expressions, and "math mountains" show children how sums "climb higher." Worksheets with gardens that add crops together also help students to conceptualize addition.
Basic geometry is the subject of several units and includes exercises on finding the area of quadrilaterals, measuring triangles and understanding the importance of perimeters and shapes. Time-telling lessons involve completing practice problems with clocks, and the second-graders learn about seconds, minutes, hours, days, weeks and months.
The school year finishes with students learning about metric measurements, weight, mass, temperature and capacity. These concepts prepare students for science and future math principles, including chemistry, physics, geometry and algebra.
"Math Expressions" is Houghton Mifflin's math curricula from kindergarten through grade five. Online resources are available to supplement in-class textbooks, and students and families can easily access additional resources on the company's website.Learn more about Homework Help
