What’s Included:

 

⭐ Lesson Slide (Slide 1)

Introduce and teach:

• What subtraction means
• How quantities change when objects are taken away
• How to use the “use your fingers” subtraction strategy

👆 Use this slide for direct instruction before independent practice.

 

⭐ Subtract with Your Fingers (Slides 2–3)

Students practice subtraction by:

• Using digital fingers to model subtraction problems
• Dragging numbers to fill in the correct answers
• Solving 6 subtraction sentences per slide

This activity helps build early subtraction understanding using concrete representations.

 

⭐ Subtraction Strategies Overview (Slide 4)

Students are introduced to five subtraction strategies:

• Use your fingers
• Use manipulatives
• Draw a picture
• Count back
• Use a number line

These strategies help students understand there are multiple ways to solve subtraction problems.

 

⭐ Use Manipulatives (Slides 5–15)

Students:

• Solve subtraction sentences
• Use digital manipulatives to represent the problem
• Type the answer into the yellow box

This activity supports concrete modeling and visual subtraction strategies.

 

⭐ Draw a Picture Strategy (Slides 16–26)

Students:

• Draw or cover pictures to represent subtraction
• Cross out objects being taken away
• Type the remaining quantity

This activity helps students visualize subtraction as taking away.

 

⭐ Count Back Strategy (Slides 27–29)

Students:

• Practice the counting back strategy
• Solve multiple subtraction sentences per slide
• Drag numbers to show the correct answer

This strategy supports mental math development.

 

⭐ Use a Number Path (Slides 30–40)

Students:

• Solve subtraction sentences using a digital number path
• Move the bunny backward along the number path
• Type the final answer

This builds understanding of subtraction as moving backward along a number sequence.

 

⭐ Use a Number Line (Slides 41–51)

Students:

• Solve subtraction sentences using a digital number line
• Move the frog backward along the number line
• Type the final answer

This builds understanding of subtraction as moving backward along a number sequence.

 

⭐ Word Problems (Slides 52–61)

Students:

• Read subtraction word problems
• Use moveable pictures to model the situation
• Complete the subtraction sentence

This activity strengthens reasoning, modeling, and mathematical communication.

 

⭐ Make Your Own Subtraction Problems (Slides 62–66)

Students:

• Create their own subtraction sentences
• Type numbers into the equation
• Use digital manipulatives to solve the problem

 

Manipulative themes include:

• Kittens
• Animals
• Dinosaurs
• Cars
• Building bricks

Encourages creativity and deeper mathematical thinking.

Tech Tips:

• Use in EDIT mode (not Present mode) so movable pieces work.
• If assigning in Google Classroom, students using iPads/tablets must have the Google Slides app installed to manipulate pieces.
• You may also download the slides as a PowerPoint file to use on a SMARTBoard.
