Why get the bundle
- Seeing the missing number in games and cards helps children think about the whole equation.
The problem
2 + ? = 6 and the answer is 8
Children see two numbers and an equals sign and add them. A question mark in the middle changes the job.
Adding the two numbers shown
2 + ? = 6 becomes 8 when a child adds 2 and 6. The question is how many more to make 6.
Counting from the start
To find the partner, children can count up from 2 on fingers. It works but takes a long time.
The question mark
The ? is just a number waiting to be found. Some children treat it as a sign or leave it blank until it is read as 'how many?'
Each item has a hidden number to find: 7 + ? = 8. Children count up from the first number to the total, or use the fact family.
What’s inside
30 questions, one per slide.
Students type straight into the box — no printing, no cutting.

Questions
Before you buy.
Is it subtraction?
Children can use subtraction, but the problems are framed as addition.
What if my child adds the two?
Ask them to check by putting the answer in: does 2 + 8 make 6?
How do I get the file?
The download link appears right after checkout and lands in your inbox at the same time. One PowerPoint file you can open in Google Slides.
Can I share it with my class?
Yes — one teacher can use it with their own students, this year and next. Sharing the file with other teachers needs a separate license.
Do I need Google Slides?
No. The file is a PowerPoint (.pptx). It opens in PowerPoint, and in Google Slides once you upload it to Google Drive.
What if it isn’t right for us?
Email support@pencillane.com within 30 days and we refund the full $4.50. No form, no questions.
