Read the addition, explain a strategy, then say the sum. Check with a reference card after giving an answer.
13 cards on 4 pages in the default deck. The image shows its first page. Adding the reference set produces 8 PDF pages in total.
The complete deck has 10 cards through 9 or 13 cards through 12. Density changes the number of sheets, not the facts.
The ready-made image shows page 1; each PDF contains the full deck. Cards with references adds a separate complete set with answers or annotations. These are not mirrored duplex backs and make no front/back alignment promise. Print at actual size and cut along the optional guides.
Customize this deckWhat changes the deck?
Fixed decks keep every card when density changes. Ordered fixed decks ignore the seed; choose Shuffled to use the seed for a different order. Time, number and money-amount decks generate a count from pages × density and can contain repeats.
Learning objective
What this activity builds
Explain and recall addition facts for a chosen first addend.
Worked example
How can you work out 3 + 8?
11.
Start at 8 and count on three: 9, 10, 11. Switching the addends can make the counting easier.
Teaching notes
Make the practice count
- Choose a fixed addend from 1–12. Every second addend from 0 to the selected endpoint appears once.
- For teacher-led first practice, use fixed addend 1 with partners through 9, and build unfamiliar sums with counters.
- Ordered practice reveals patterns; choose shuffled order before changing the seed to mix a fixed deck.
