Students will be able to use a starting number and count on to find the solution to an addition problem. Students will be able to construct number sentences that include a solution to an addition problem.
Introduction (5 minutes)
- Begin the lesson by leading the class in a counting clap.
- Use the numbers on the introductory SMART Board slides or the Cherry Counting posters to start at any cherry.
- Count until all the cherries have been counted. For example, on one slide or poster, start on the sixth cherry and have the students count from six on until all cherries have been counted.
- Have your students clap each time they say a number.
- Explain to your students that they will find the sum, or the total of the numbers added together.
Explicit Instruction/Teacher Modeling (5 minutes)
- Using either the SMART Board file or one of the Cherry Modeling posters, show the process of counting the number of cherries in the first basket.
- Write that number above the first basket on the line. Write a plus sign in between the two baskets.
- Direct your students to count the number of cherries in the second basket.
- Repeat the process of counting, but do it together as a class.
- Show your class how to determine the sum by combining the two baskets of cherries, beginning with the first number and counting on to find the total number of cherries.
- Repeat the process with the additional SMART Board slides or posters.
Guided Practice/Interactive Modeling (10 minutes)
- Invite your students to come up to the interactive whiteboard and create solutions to addition problems shown on the flash cards.
- On the interactive whiteboard, have your students move scoops of ice cream on the cones to find the total number of scoops.
- Instruct your students to write the number of scoops on each cone. Have them write number sentences and add the numbers together to find the total.
- If you don't have an interactive whiteboard, you can also use the ice cream manipulatives to lead your students in the activity.
- After displaying addition equations on the board, ask your students to participate in modeling the solutions in front of the class. For example, have them count out six ice cream scoops to show the sum.
Independent Working Time (10 minutes)
- Have your students complete either the Ice Cream Scoops worksheet or the Cherry Math worksheet, depending on your preference.
- For students who might need additional support, provide manipulatives for your students to use during their calculations.
- Refer to the Cherry Counting posters and the basket example if students need help.
- Enrichment: Using cutouts of cones and ice cream scoops, have your students create two different cones and add the number of scoops together, creating an addition number sentence in the process. If students do multiple number sentences, they can create a poster of their addition facts. Alternatively, using Google Draw or another software, ask your students to create two groups of objects and add them together.
- Support: Work with students individually, using manipulatives (cherries and ice cream scoops) and flash cards to reinforce addition concepts. Alternatively, you can give your students some dominoes. Ask your students to find addition facts inside the dominoes. For example, add the numbers on both sides of the dominoes. Have students write down their addition number sentences in math journals or on individual index cards.
- Let your students use Google Draw or another image software to create drawings that match addition problems.
Assessment (5 minutes)
- Display one or more of the addition flash cards, or provide a different addition problem.
- Ask your students to write the number sentences on their index cards, and have them show their work by drawing circles to represent the two numbers they are adding. For example, if the number sentence is 3 + 6 = 9, instruct them to draw three circles, six circles, and nine circles.
Review and Closing (5 minutes)
- Conclude the lesson with a sweet treat! Give each student seven cherries, raisins, or other small pieces of fruit.
- Have your students practice creating different combinations of addition facts using the sweet treats.
- Ask your students to write their number sentences on individual whiteboards or paper.
