150 Card Deck
Magnetic box · 150 cards · 30-page guide
Spark cards to retrieve, Shift cards to reflect. Most run in a spare ten minutes and need nothing but pen, paper or the board.
30-day guarantee, and schools can pay by invoice.
Two systems
Spark cards for retrieval, Shift cards for reflection, and a teacher guide you can download free.
3 to 25 mins
128 of the 150 run in ten minutes or less, with a median of eight. Three are ongoing routines rather than timed activities.
87 need nothing
87 cards need nothing but pen, paper or the board. 13 ask you to prepare something, and the card tells you which is which.
66 low-energy
66 cards are pitched low for a Friday period, 44 medium and 40 high, so you can match the card to the room.
22 studies
Every card names the study it rests on, drawn from 22 studies across retrieval practice, spaced practice, elaboration, dual coding and metacognition.
NZ teachers
Written by NZ teachers and tested in NZ classrooms.
How it works
Every card has a front and a back. The front is the activity: three steps, what you need, and a time estimate. The back is the why: the research behind it and the command word it practises.
A Spark card at the start of a lesson gets prior knowledge back out. One mid-lesson shows you the gaps before they settle. A Shift card at the end asks students what stuck.
Built on the evidence
- Retrieval practice (Roediger & Karpicke): pulling from memory strengthens it far more than re-reading
- Peer learning (Mazur, Nuthall): students learn deeper from peers wrestling with the same misconception
- Metacognition (Cowie, EEF): students as agents in the feedback loop, not just receivers
- Formative assessment (Hattie): specific, timely, actionable feedback closes the loop
How it fits a normal teaching week.
Warm up fast
Five groups each prep a 30-second summary of a body system. One group is secretly the Imposter, planting one wrong fact: "the heart oxygenates the blood." After all five present, the class votes, but only a vote that names the exact error counts.
Mid-lesson lift
Hands on head for true, hips for false: "correlation proves causation." Half the room commits before thinking, which is exactly the point. Energy's back in twenty seconds.
Surface the gaps
Students draw the causes of the New Zealand Wars from memory, then check their notes in a different colour. Whatever they add in that second colour is the gap.
Consolidate
The class chains facts about the water cycle, each student naming the connection to the one before. One wrong link breaks the chain, and the class has to find where.
Reflect and close
Before Monday's test, students rate their understanding 0 to 10 on a sticky note. "Standard deviation" comes back a 4, "mean and median" a 9. Next week's revision is ready to go!

Spark vs Shift at a glance
Spark gets knowledge out. Shift checks what stuck. Most lessons have room for one of each.
| Feature | ⚡ Spark | ⇄ Shift |
|---|---|---|
| Purpose | Get knowledge OUT of heads | Find out what STUCK |
| Research base | Retrieval practice, spaced repetition | Metacognition, calibration |
| Activity type | Quiz, game, movement, recall | Self-audit, reflection, writing |
| Group size | Whole class, teams, or solo | Solo or paired |
| Time to run | 10+ minutes | 10+ minutes |
| Energy level | High (when room needs it) | Quiet and thoughtful |
| Best for | Warm-ups, transitions, reinforcement | Exit ticket, end of lesson, check-in |
What it looks like in a real lesson.
One Spark card, run in a Year 11 class with ten minutes left.
You pull "The Imposter"
The bell is close. You read the card: five groups get sixty seconds to prepare a summary of today's content. One group, chosen at random, is handed a slip telling them to hide one deliberate error.
Each group presents
All five summaries run back to back, no interrupting. The class listens for the plant, not just the wrong-sounding line. You walk and listen.
The class votes and names it
The card told you what to watch for: a vote only counts if the student names the exact error, not just the group. That precision is what tells you who was really listening.
The bell goes
Ten minutes turned into a full-class retrieval activity and formative assessment, without any Sunday night prep.
Research: retrieval practice and the testing effect (Roediger & Karpicke, 2006). Named on the back of the card.
Yes. Across every subject.
The strategies are subject-agnostic. You bring the content, the card brings the structure. A few examples of how teachers adapt one card to their room.
"The Imposter" on a set text: five groups each summarise a chapter. One group's summary hides a planted error about the plot. The class has to catch it and name the exact line that's wrong.
"The Chain" on solving quadratics: each student states the next step and names the rule behind it, out loud, until someone can't and the chain breaks.
"The Confidence Thermometer" after a titration practical: students rate their understanding 0 to 10 on a sticky note, post it to the board, and the spread shows exactly where to re-teach.
"The Concept Court" with the 1981 Springbok Tour on trial: was it a sporting event or a civil rights moment? Each side has to argue from evidence.
A retrieval race on this week's kupu, then "The Parking Lot" to flag which words are still shaky before the test.
"The Teach-Back" after a rugby drill or a waiata performance: explain the technique to a partner well enough that they could do it too.
What makes the deck work
Pen and paper, no guilt
You can pull a card with a few minutes left in the lesson and it still works. Most need nothing but pen, paper or the board, and the 13 that need preparation say so on the card.
Works for every subject
English, maths, science, languages, social sciences. Swap in your content. The steps stay the same.
You know why it works
Every card names the research. You can explain to a head of department, to parents, to yourself why retrieval and reflection matter.
Built for NZ classrooms
Written by NZ teachers, tested in NZ schools, aligned to the New Zealand Curriculum.
What the deck covers
Every card names the command word it practises, the same words that appear in exam questions and marking schedules. The line prints on the back of the card.
