Abstract
This mathematics STRAND project is centered around 2nd grade SOL 2.5 and
2.6 computation and estimation. The activities provided in this project
focus on helping students grow in their knowledge of adding and
subtracting. It also teaches students to recognize and use the
relationship between addition and subtraction to solve single-step
practical problems, with whole numbers to 20. Students practice
adding and subtracting a variety of ways during the STRAND, and
these activities support a variety of learners. This project provides
several activities, notetaking devices, and assessments that will
support students in growing in their knowledge of addition and
subtracting.

Mathematics Strand Project
Grade Level: 2nd
Topic: Computation and Estimation
SOL: 2.5 The student will
a) recognize and use the relationships between addition and subtraction to solve
single-step practical problems, with whole numbers to 20; and
b) demonstrate fluency with addition and subtraction within 20.
2.6 The student will
a) estimate sums and differences;
b) determine sums and differences, using various methods; and
c) create and solve single-step and two-step practical problems involving addition and
subtraction.
Essential questions: 1. Retell this problem in your own words. 2. What do you have
to find out? 3. How can you use a ten-frame to help with addition?

Notetaking Device
VA Mathematics SOL: 2.5 The student will solve practical problems that involve
adding and subtracting.
Graphic Organizer: A graphic organizer was created as a notetaking device for students to
use for this mathematics STRAND. The graphic organizer instructs students on how to add
and subtract
