Welcome to Subtraction! – Subtraction means taking away – It helps us know what’s left – We’ll use cube trains for counting – Cube trains are blocks stuck together to show a number – Let’s find out how many are left! – If we start with 5 cubes and take 2 away, how many are left? | This slide introduces the concept of subtraction to Pre-K students in a simple and engaging way. Subtraction is explained as the process of taking away items from a group and finding out how many items remain. Cube trains, which are a series of connected blocks, will be used as a visual and tactile aid to help students understand the concept of ‘taking away.’ Encourage the children to visualize the subtraction by physically removing cubes from the train. For example, if there are 5 cubes and you take away 2, ask the students to count how many cubes are left. This hands-on activity will help solidify their understanding of basic subtraction. Make sure to use clear and simple language, and be ready to assist the children in counting the remaining cubes.

Understanding Subtraction: Cube Trains – Subtraction means taking away – When we subtract, we take some away from a total number. – Find out how many left – If we start with 5 blocks and take away 2, we have 3 left. – Like eating cookies – Imagine having 5 cookies; if you eat 2, you have 3 cookies left. – Cube trains show subtraction – Using blocks to represent cookies, we can see how many we have after eating some. | This slide introduces the concept of subtraction to Pre-K students using the analogy of eating cookies to make it relatable. Subtraction is explained as the process of taking away from a group and finding out what’s left. Use cube trains or blocks to visually demonstrate subtraction by removing blocks and counting the remaining ones. This hands-on activity helps students visualize the concept and understand that subtraction tells us how many items are left after some are taken away. Encourage students to use physical objects like blocks or toys to practice subtracting up to 5 and to share their results with the class.

Understanding Subtraction Sentences – Subtraction sentence structure – It has numbers and a minus sign (-). – Example: 5 – 2 = 3 – This shows taking 2 from 5 equals 3. – Taking away with subtraction – If we remove 2 cubes from 5, we see 3. – Counting what’s left – After subtracting, we count the remaining cubes. | This slide introduces the concept of subtraction sentences to Pre-K students using simple and relatable terms. Start by explaining that a subtraction sentence is a way to show taking away using numbers and a minus sign. Use physical objects like cube trains to demonstrate subtraction visually. For example, show a train of 5 cubes, remove 2, and count the remaining 3 cubes with the class. Emphasize that the number after the minus sign is what we take away, and the number at the end is what we have left. Encourage students to use their fingers or classroom objects to practice creating their own subtraction sentences.

Let’s Make a Cube Train! – Cube trains visualize subtraction – Build a train with blocks – Use colorful blocks to make a train – Remove blocks from the train – Take away 1 or 2 blocks, what’s left? – Count the remaining blocks – Practice counting with the blocks left | This slide introduces the concept of subtraction to Pre-K students using a hands-on activity with cube trains. Start by explaining that a cube train can show us how subtraction works. Have the students build a train using a set number of blocks, such as 5. Then, instruct them to remove a certain number of blocks, like 1 or 2, and count how many blocks are left. This visual and physical method of teaching subtraction helps young learners grasp the concept of ‘taking away’ in a fun and interactive way. For the activity, provide different scenarios for subtraction, such as removing different numbers of blocks or starting with different lengths of trains, to reinforce the concept.

Subtraction with Cube Trains – Start with a 5-cube train – Take away 2 cubes – How many cubes left? – After removing 2, we count what’s left to find the answer – Let’s count the remaining cubes – Counting together helps us learn subtraction | This slide introduces the concept of subtraction using a tangible example of cube trains. Start with a visual representation of a train made of 5 cubes. Explain that subtraction means taking some away. Physically remove 2 cubes from the train and ask the students how many cubes are left. Encourage the students to count the remaining cubes aloud together. This interactive approach helps solidify the concept of subtraction by visualizing the process and actively engaging in finding the solution. For the activity, you can have different sets of cube trains for each student or group, and you can vary the number of cubes taken away to practice different subtraction scenarios up to 5.

Practice Time: Subtraction with Cube Trains – Build a 5-cube train – Remove 1, 2, or 3 cubes – Count the cubes left – Understand subtraction – Removing cubes helps learn subtraction | This slide is an interactive activity for students to practice subtraction by physically manipulating objects. Provide each student with 5 cubes and instruct them to build a train. Then, ask them to remove 1, 2, or 3 cubes and count the remaining cubes. This hands-on approach helps students visualize the concept of subtraction as ‘taking away’. Encourage them to verbalize their actions, for example, ‘I had 5 cubes, I took away 2, now I have 3 cubes left’. This reinforces the subtraction process and the understanding that subtraction is about finding out ‘how many are left’. Possible variations of the activity could include using different colored cubes for subtraction, or having students record their findings on paper to share with the class.

Class Activity: Cube Train Subtraction – Build your own cube train – Partner up for subtraction fun – How many cubes remain? – After subtracting, count the cubes left in your train – Share with the class – Discuss the number of cubes left with your classmates | This interactive class activity is designed to help Pre-K students understand the concept of subtraction in a hands-on way. Provide each student with a set of cubes to build their ‘cube train’. Students will then work with a partner to practice subtracting cubes from their trains. After the subtraction, they should count how many cubes they have left. Encourage them to communicate their results with their partner and then share with the class. This activity not only teaches subtraction but also fosters communication and social skills. Possible variations of the activity could include: using different colored cubes for subtraction, creating patterns with the cube train before subtracting, or having a ‘conductor’ who calls out how many cubes to subtract.

Subtraction Success with Cube Trains! – Subtraction means taking away – Cube trains help us visualize this – Just like removing a block from a train – Practice makes perfect – Use toys to practice subtracting at home – You’re becoming subtraction stars! | Congratulations to the class for mastering the basics of subtraction using cube trains! It’s important to reinforce that subtraction is simply the process of taking away one number from another. Cube trains are a great visual aid to help young learners understand this concept. Encourage the students to continue practicing at home using their own toys to subtract, making the learning experience fun and practical. Recognize their efforts and progress by calling them ‘subtraction stars’, fostering a sense of achievement and encouraging a positive attitude towards math.
