- Introduce the concept of subtraction by using examples of taking away objects from a group.
- Explain that subtraction means finding out how many are left after some are taken away.
- Show students how to use connecting cubes to represent subtraction sentences, such as 9 take away 3 is 6. 2. Model the process by creating a group of 9 connecting cubes, then taking away 3 cubes, and showing the remaining 6 cubes.
- Explain that the number of cubes left is the difference, and this is the answer to the subtraction sentence.
- Introduce the subtraction sentence cards and demonstrate how to read and solve them using connecting cubes.
- Divide students into pairs and provide each pair with a container of connecting cubes and a set of subtraction sentence cards.
- Instruct students to work together to use the connecting cubes to represent and solve each subtraction sentence.
- Circulate around the room, providing support and guidance as needed, and checking for understanding.
- Have students work independently to solve subtraction sentences using connecting cubes.
- Provide each student with a new set of subtraction sentence cards.
- Monitor students' progress, providing support and assistance as needed.
- Assign students a homework sheet with subtraction sentences to solve using connecting cubes.
- Encourage students to discuss the activity with their parents and practice solving subtraction sentences at home.
- Provide each student with an exit card.
- Instruct students to write a subtraction sentence and draw a connecting cube model to represent their sentence. 3. Collect the exit cards and review them to assess students' understanding of representing subtraction sentences using connecting cube models.
- Formative assessments will be conducted during the lesson to monitor students' understanding of representing subtraction sentences using connecting cube models.
- The exit card and progress monitoring assessments will be used to determine students' mastery of representing and completing subtraction sentences using connecting cube models.
- Review the key concepts of subtraction and using connecting cubes to represent subtraction sentences.
- Ask students to share their favorite subtraction sentence from the lesson and explain how they used connecting cubes to solve it.
- Students can practice addition using connecting cubes to represent addition sentences.
- Students can explore more complex subtraction problems, such as subtracting from numbers larger than 10.
- Students can use other manipulatives or objects to represent subtraction sentences, such as counters, beads, or LEGO bricks.
- For students who struggle with fine motor skills, larger and easier-to-grasp cubes can be used.
- For students who need extra support, a visual aid or diagram can be provided to help them understand the concept of subtraction and how to use connecting cubes to represent subtraction sentences.
- Pair struggling students with a peer who has demonstrated mastery of the concept, allowing them to work together and provide support during guided and independent practice.
- Provide additional practice opportunities and one-on-one instruction for students who require more time to grasp the concept.
No Video Available
- Encourage students to use verbal explanations while solving subtraction problems with connecting cubes to reinforce understanding.
- Use real-life examples to illustrate subtraction scenarios, making the concept more relatable for students.
- Introduce a variety of subtraction strategies (e.g., counting back, using a number line) to cater to diverse learning styles.
- Some students may think that subtraction always involves taking away objects from the left side, rather than identifying the specific number to be subtracted.
- Students may confuse subtraction with addition, attempting to combine cubes instead of taking them away.
- Some students may believe that larger numbers cannot be subtracted from smaller numbers, not yet understanding the concept of negative numbers.
Common Core Standard:
K.OA.A.1 Part 2 - Represent subtraction with objects, fingers, mental images, drawings, sounds (e.g., claps), acting out situations, verbal explanations, expressions, or equations.
