Prerequisite Skill
Materials and Preparation
- Number line charts (0-10) for each student
- TeachTastic Worksheet Pack for Adding by Counting On
- Whiteboard and markers
- Counting manipulatives (e.g., counters, cubes)
- Interactive number line (optional for digital learning)
Learning Objectives
- Students will understand the concept of adding by counting on.
- Students will be able to use a number line to add two numbers by counting on.
- Students will solve addition problems with sums up to 10 using the counting on strategy.
Introduction
Begin the lesson by discussing with students how we can find the total when adding two numbers. Introduce the concept of "counting on" as a strategy to add numbers. Demonstrate this with an example problem using a number line: "If we start at 2 and count on 3 more, what number do we land on?" Show how to move along the number line to reach the sum.
Explicit Instruction/Teacher modeling
Explain that when we add by counting on, we start with the first number and count up by the number we are adding. For example, in the problem 2 + 3, we start at 2 on the number line and count on 3 more steps to reach 5. Show this step-by-step on the whiteboard using a number line.

Guided Practice
Distribute number line charts and the TeachTastic Worksheet Pack for Adding by Counting On to each student. Work through several problems together, guiding students as they use the number line to count on and find the sum. For instance, solve problems like 3 + 4 and 5 + 2, ensuring students are following the steps accurately.
Independent Practice
Have students complete additional problems from the TeachTastic Worksheet Pack independently. Problems should include various sums up to 10, allowing students to practice the counting on strategy on their own.
Differentiation
Support
- Small Group Instruction: Work with students who need extra help in small groups, using manipulatives to visually represent the counting on process.
- Peer Tutoring: Pair students who grasp the concept with those who need additional support for peer tutoring sessions.
Extension
- Challenge Problems: Provide problems with sums greater than 10 for students who have mastered counting on with sums up to 10.
- Interactive Games: Incorporate interactive counting games that involve counting on to higher numbers.
Assessment
Evaluate students' understanding through their participation in guided practice, accuracy in independent practice, and responses on the exit ticket. Use specific worksheets from the TeachTastic Worksheet Pack to assess each student's ability to add by counting on.
Review and closing
Summarize the key points of the lesson, emphasizing the counting on strategy. Address any common misconceptions and answer any questions students may have. Encourage students to share their observations and experiences with the lesson.
Misconceptions
- Misunderstanding the Starting Point: Students may start counting from 1 instead of the first number in the problem. Remind them to start from the given number.
- Skipping Numbers: Students might skip numbers while counting. Practice counting sequentially on the number line to avoid this mistake.
- Incorrect Counting Sequence: Ensure students understand the correct order of numbers and do not count backward or out of sequence.
