Welcome to Subtraction! – Greetings little mathematicians! – Today’s lesson: learning to take away – We’ll use objects like cubes to subtract – Subtraction: a numbers magic trick – Imagine having 5 candies and eating 2 – We’ll practice with numbers up to 5 – How many candies are left? Let’s find out! | This slide is designed to introduce Pre-K students to the concept of subtraction in an engaging and relatable way. Start by greeting the students warmly to create a welcoming learning environment. Explain that subtraction is a process of taking away and can be thought of as a magic trick where numbers change when we take some away. Use tangible objects like cubes or candies to illustrate subtraction, as this will help them understand the concept better. Encourage the children to visualize the subtraction process with real-life examples. The goal is to make them comfortable with the idea of ‘less than’ using numbers up to 5. During the class, have hands-on activities where students can physically remove items and count what remains to solidify their understanding.

Understanding Subtraction: Taking Away Cubes – Subtraction means taking away – Start with a number, then take away – Like 5 cookies, eat 1, count remaining – If you have 5 cookies and you eat 1, you have 4 left. – Practice with cubes: 5 take away 1 – Use 5 cubes, remove 1, and see 4 cubes are left. | This slide introduces the concept of subtraction to Pre-K students using tangible examples. Subtraction is explained as the process of taking away one number from another. To make it relatable, use the example of having 5 cookies and eating 1, then asking the students how many are left to help them understand the concept of ‘taking away’. Encourage hands-on practice with physical objects like cubes. Have 5 cubes in front of each student and guide them to take 1 away, then count the remaining cubes. This visual and tactile approach helps solidify the concept of subtraction in young minds.

Take Away Cubes: Learning Subtraction – Subtraction with cubes – Start with 5, take 1 away – If you have 5 apples and eat 1, how many are left? – Count what’s left – After taking 1 away, we count the remaining cubes. – Practice together – We’ll use our cube friends for a fun activity! | This slide introduces the concept of subtraction to Pre-K students using a hands-on approach with cubes. Start by explaining that subtraction means taking away. Show them 5 cubes, remove one, and then count the remaining cubes together. Use simple language and real-life examples like apples to help them understand. During the activity, guide the students to subtract by taking away cubes and counting what’s left. Encourage participation and assist any students who need help. The goal is to make subtraction a fun and interactive experience.

Let’s Practice Taking Away! – Start with 5 cubes – Take away 2 cubes – Observe: 5 cubes – 2 cubes = ? – Guess the result of taking away 3 – Can you predict: 5 – 3 = ? – Understand subtraction | This slide is designed to introduce Pre-K students to the concept of subtraction in a tangible and interactive way. Begin with a hands-on demonstration using 5 physical cubes. Show the students what happens when you physically remove 2 cubes and ask them to count the remaining cubes. This visual and physical representation helps them understand subtraction as ‘taking away’. Next, encourage them to make a prediction about what happens if you take away 3 cubes from the original 5. This exercise not only teaches them subtraction but also encourages critical thinking and making predictions. For the activity, provide different scenarios or sets of cubes for the students to practice taking away various numbers up to 5. Guide them through the process and ensure they understand the concept of ‘less than’ as a result of subtraction.

Subtraction is Fun! – Subtraction in daily life – It helps us find out how many items remain after some are taken away. – Sharing with friends – If we have 5 candies and give 2 to a friend, we use subtraction to find out how many are left. – Counting what’s left – After taking away, we count the remaining items to know the total. | This slide introduces the concept of subtraction to Pre-K students in a fun and relatable way. Explain that subtraction is a part of everyday life and can be used in various situations, such as sharing toys or snacks with friends. Use tangible examples like candies or blocks to illustrate the concept. Encourage the children to think of subtraction as a simple action of taking away and then counting what remains. This will help them understand the basic idea without getting overwhelmed by numbers. During the class, engage the students with hands-on activities where they physically remove items and count the leftovers to reinforce the concept.

Cube Take Away Activity! – Start with 5 cubes each – Play the take away game – How many left after 1, 2, or 3 taken? If you take 1 away from 5, you have 4 cubes left! – Share your results with the class | This interactive class activity is designed to introduce Pre-K students to the concept of subtraction in a tangible and engaging way. Distribute 5 cubes to each student and guide them through the process of ‘taking away’ a certain number of cubes, then counting how many are left. Encourage them to verbalize their actions, e.g., ‘I have 5 cubes, I take away 2, and now I have 3 cubes left.’ This helps solidify the concept of subtraction. Have a few different scenarios ready for students who may grasp the concept quickly and need additional challenges. For example, ask them what happens if they start with 5 cubes and take away all 5. After the activity, facilitate a discussion where students can share their findings and reinforce their understanding of subtraction.
