LESSON INSTRUCTION
INTRODUCTION
- Review the concept of addition with the students.
- Ask the students to tell you what they know about addition.
- Introduce the concept of fluently adding within 10 using mental strategies.
- Display flashcards for numbers 1-10 and ask the students to say the number that comes after a given number.
INSTRUCTION
-
- Introduce and explain the mental strategies for adding within 10:
- Counting on: Start with the larger number and count up to the sum.
- Doubles: If you know the doubles facts (e.g., 2+2=4), you can use them to solve addition problems (e.g., 3+3=6).
- Near doubles: If you know a doubles fact and the number that is one more or one less than the other addend, you can use it to solve the problem (e.g., 3+4=7, because 3+3=6 and 6+1=7).
- Model how to use each strategy to solve addition problems within 10.
- Practice using each strategy with the class, using math manipulatives.
GUIDED PRACTICE
- Divide the class into small groups and give each group a set of addition problems.
- Have the students work together to solve the problems using the mental strategies they learned.
- Circulate around the room to provide support and guidance as needed.
INDEPENDENT PRACTICE
- Have the students complete a worksheet with word problems that require them to use mental strategies to add within 10.
- Encourage the students to use the mental strategies they learned during the lesson.
- Monitor the students' progress and provide support as needed.
HOMEWORK
- Provide students with a worksheet that contains addition problems within 10.
- Instruct students to use mental strategies to solve the problems.
- Encourage students to explain their mental strategies and how they arrived at their answers.
- For extra practice, students can create their own addition problems within 10 and solve them using mental strategies.
EXIT TICKET
- Provide each student with a whiteboard and marker.
- Instruct students to write an addition problem within 10 and solve it using a mental strategy.
- Collect the exit cards and review them to determine if the students have met the lesson objective.
ASSESSMENT
- Formative assessments will be conducted during the lesson to monitor students' understanding of mental strategies for adding within 10.
- The exit card and progress monitoring assessments will be used to determine students' mastery of the lesson objective.
CLOSURE
- Review the mental strategies for adding within 10.
- Ask students to share which mental strategy they found most helpful and why.
- Encourage the students to continue practicing mental strategies.
EXTENSION
- Students can practice adding within 20 using mental strategies.
- Students can create their own addition problems and solve them using mental strategies.
- Students can practice adding within 10 using timed challenges to increase fluency.
INTERVENTION
- For students who struggle with fine motor skills, provide larger math manipulatives that are easier to manipulate.
- For students who need extra support, provide additional examples and practice problems that build on each mental strategy.
- For students who need more challenge, provide more complex word problems that require multiple mental strategies to solve.

TEACHING TIPS
- Encourage students to explain their mental strategies and how they arrived at their answers.
- Use visual aids, such as ten frames and number lines, to help students understand the concept of addition.
- Provide frequent opportunities for students to practice mental strategies, both individually and in small groups.
STUDENT MISCONCEPTIONS
- Counting all fingers/toes or objects instead of using mental strategies
- Forgetting to start with the larger number when using the counting-on strategy
- Assuming that doubles always have the same sum (e.g., 5+5=10, but 6+6 is not equal to 10)
STANDARD
Common Core Standard:
K.OA.A.5 - Fluently add and subtract within 5.
