First and last name — this is how your teacher gives you credit.

Printable sheets
Black and white, no color ink needed. Each one opens your printer dialog — choose Save as PDF if you'd rather keep a copy. Answer keys print as their own page.
Assign a practice set
Pick a level and share the link. Students sign in with name + period, answer 12 questions built from their own name, and hand you a code. Multiple choice only earns its point if the first answer is right.
Grade assignment codes
Paste every student code below — one big mess is fine. You get a roster sorted by period, then last name.
Check one practice code
For free-practice codes (PTE-…) students earn outside an assignment.
Codes carry the student's name, level, score, and the date, so they can't be swapped between students. Nothing is uploaded — everything runs on the device, and the page works with the wifi off.
Standards this covers
8th Grade — S8P1
Structure of the atom (protons, neutrons, electrons), reading a periodic table square, families and groups, metals vs. nonmetals vs. metalloids, and using position to predict properties. High School — SPS1, SPS2
Electron arrangement and energy levels, valence electrons, periodic trends in atomic radius, ionization energy and electronegativity, predicting ion charge, and predicting ionic vs. covalent bonding from position.
