Math Word Problems - Addition and Subtraction for Kindergarten and First Grade

This free version includes the first level. You can purchase the full version (which includes the second level) through an in-app purchase.

This app is designed to be used in a classroom or home setting. The app is designed to be used independently but can also work well where a teacher or family member is available to work through problems and discuss problem-solving strategies with the student(s). These word problems are designed with the rigor of the following educational standards in mind:

-- American Curriculum (Common Core) --

CCSS.Math.Content.K.OA.A.2 Solve addition and subtraction word problems, and add and subtract within 10, e.g., by using objects or drawings to represent the problem.

CCSS.Math.Content.1.OA.A.1 Use addition and subtraction within 20 to solve word problems involving situations of adding to, taking from, putting together, taking apart, and comparing, with unknowns in all positions, e.g., by using objects, drawings, and equations with a symbol for the unknown number to represent the problem.

-- Canadian Curriculum --

This app supports mathematics learning in the early years across Canada. The app connects to curriculum in the following areas:
• number sense as it relates to problem solving in addition and subtraction of whole numbers to 20
• addition and subtraction using a variety of concrete and visual representations
• processes for learning mathematics

The app includes two levels: questions that go up to 10 and questions that go up to 20.

Each question includes the following:
• A space to sketch the problem and write the full equation.
• A ten frame and number path for students to show their work.
• An answer keyboard.

After successfully choosing the answer, the correct equation is briefly shown on the screen in large format to help reinforce the full equation. The app tracks how many questions out of 10 the students answer correctly on their first attempt.

We’d love to hear how you are using the app in the classroom and/or home. [email protected] Thank you.

The Number Path Explained

This app uses a number path instead of a number line. Research has shown that number lines,which use a model of length,can be confusing for young children and often lead to the following common errors: Some children start their count with zero and are off by one. Some students count the space between the numbers. When they try to find the answer, their finger is between two numbers so they are not sure which number to choose.

A number path is a counting model. Each number is represented within a rectangle and the rectangles can be clearly counted. Further, a number path provides a more supportive model of numbers, which is important as we want models that consistently help students build confidence and accurately solve problems. Therefore, it is often best for students to use number paths, instead of number lines, until 2nd grade (Fuson, et.al., 2009).
