TI-84 Scavenger Hunt

Learn the calculator by finding, trying and explaining its tools. Twelve short missions move from the home screen to graphing, statistics, variables, matrices, modes and error recovery.

Zone 1

Find & calculate

Get comfortable with the home screen, recall, powers and negative values.

4 missions
01

Warm up the home screen

Enter 84 + 16 and press ENTER.

Need a hint?

Type the expression exactly as written, then press ENTER.

02

Recall, edit, recalculate

Calculate 27 × 4. Then press 2nd → ENTER to recall the expression, change 4 to 5 and evaluate it again.

Need a hint?

The recalled expression can be edited before you press ENTER again.

03

Use the power key

Use the caret ^ key to calculate .

Need a hint?

Enter 7, press ^, enter 3, then press ENTER.

04

Negative sign detective

Compare (−4)² with −4². Which result pair is correct?

Need a hint?

Parentheses decide whether the negative sign is part of the base being squared.

Choose an answer

Zone 2

Graph & inspect

Move from an equation to a graph, a table and a useful viewing window.

2 missions
05

Graph and read a value

Enter Y₁ = 2X − 3. Use GRAPH, TRACE or TABLE to find y when x = 4.

Need a hint?

2(4) − 3 gives the value you should see.

06

Reset a viewing window

Which path restores the standard graph window?

Need a hint?

ZStandard is inside the ZOOM menu.

Choose an answer

Zone 3

Analyze & store

Use lists, variables and matrices as working tools rather than isolated features.

3 missions
07

One-variable statistics

Put 3, 5, 5, 7, 10 in L1. Run 1-Var Stats and record the mean x̄.

Need a hint?

STAT → EDIT to enter the list, then STAT → CALC → 1-Var Stats.

08

Store a value

Store 12 in variable A, then evaluate A² − 5.

Need a hint?

Use STO→, then ALPHA and the key carrying A.

09

Matrix mission

Create [A] = [[3,1],[2,5]] and calculate det([A]).

Need a hint?

For a 2×2 matrix, determinant = ad − bc. Use that to check your calculator.

Zone 4

Accuracy & fixing

Use modes and error recovery to make calculator results more dependable.

3 missions
10

Check angle mode

Set the calculator to Degree mode. Evaluate sin(30) + cos(60).

Need a hint?

Both sin(30°) and cos(60°) equal 0.5.

11

Use Goto after an error

Create a syntax error on purpose. Which error-screen choice places the cursor at the problem?

Need a hint?

The useful option jumps directly to where the calculator detected the error.

Choose an answer

12

Display-mode experiment

Evaluate 2.4 × 3.7. Then set Float to 0 and evaluate again. What changed?

Need a hint?

Float controls how many decimal places are shown; it does not rewrite the stored mathematical value.

Choose an answer

Finish line

Turn the hunt into something shareable.

Check missions as you work. Your result card updates automatically and can be shared without creating an account.

Start with Mission 1.

Result links include score, completed missions and time only — not the optional student name.

For teachers

Use it as a first-week activity, station or calculator reset.

Students can work on the interactive version, the printable version, or one can be used as a follow-up to the other.

01

Pair-friendly

Assign one calculator per pair and alternate the “driver” after each mission so both students handle the device.

02

Self-paced

Hints stay closed until students need them, while answer checking gives immediate feedback without revealing every solution at once.

03

Easy evidence

Students can submit a compact result link, PNG or PDF. The downloadable paper edition supports device-free or station use.
