The Under-$20 Back to School List
Ticonderoga #2 Pencils, 30-Count
The teacher-requested pencil for generations, and still the best. Ticonderogas sharpen cleanly, the graphite writes dark and smooth, and the erasers actually erase instead of smearing gray streaks. A 30-count box covers one kid for a semester, or grab two and stop hearing "I lost my pencil" until winter break. Pre-sharpened packs exist if mornings are chaotic enough already. Typical price: $8.99 Get it on Amazon →
Five Star 3-Subject Spiral Notebook
Five Star notebooks survive being crammed into backpacks all year — the covers are water-resistant plastic and the spiral doesn't snag on everything it touches. This 3-subject version has pocket dividers, so one notebook handles multiple classes. College-ruled and wide-ruled options are both available. It costs more than a bargain notebook and lasts about three times longer. Typical price: $7.99 Get it on Amazon →
Crayola Colored Pencils, 50 Count
Fifty pre-sharpened colors for around ten bucks. Crayola's pigment quality beats the generic packs — colors lay down smoothly and the leads don't shatter every time they meet the sharpener. Great for elementary art bins and just as useful for middle school map assignments, diagrams, and poster projects. Typical price: $9.99 Get it on Amazon →
BIC Round Stic Xtra Life Ballpoint Pens, 60-Count
Sixty pens for the price of a sandwich. These are the pens that end up scattered through every backpack, kitchen drawer, and pencil pouch by October — and at roughly a dime each, nobody cries when they wander off. Smooth-writing, reliable, and available in blue or black ink. Typical price: $6.99 Get it on Amazon →
Elmer's All Purpose Glue Sticks, 6 Pack
On practically every elementary supply list in America. Elmer's glue sticks go on smooth, dry clear, and are washable when the glue ends up somewhere it shouldn't. The 6-pack hits the sweet spot on price per stick — teachers usually ask for several, so one order covers the whole list. Typical price: $5.49 Get it on Amazon →
Texas Instruments TI-30XIIS Scientific Calculator
The standard-issue scientific calculator for middle and high school math, and it's permitted on the SAT and ACT. Two-line display, solar plus battery power, and it handles fractions, trig, and basic stats. At this price there's no reason to gamble on an off-brand calculator that might get side-eyed on test day. Typical price: $12.99 Get it on Amazon →
Sharpie Tank Highlighters, 12 Count
A full dozen chisel-tip highlighters in assorted colors. The Tank style holds plenty of ink, resists smearing over most pen ink, and lasts through a semester of study guides and annotated readings. Twelve means there's always one in the bag, one in the desk, and one to lend out. Typical price: $10.99 Get it on Amazon →
Post-it Notes, 3 in x 3 in, 12 Pads
Study flags, locker reminders, textbook annotations, notes on the fridge — Post-its do it all. The genuine 3M version sticks and re-sticks without curling or falling off the page, which is exactly where the cheap knockoffs fail. Twelve pads should comfortably last the school year. Typical price: $13.99 Get it on Amazon →
CamelBak Eddy+ Kids Water Bottle
Spill-proof, dishwasher-safe, and tough enough to survive being dropped off the bleachers. The bite valve means no tipping required, so it can ride in a backpack pocket without soaking the homework. It comes in tons of prints and colors, and replacement valves are cheap when they get chewed up — because they will. Typical price: $14.00 Get it on Amazon →
EASTHILL Big Capacity Pencil Case
The pencil pouch that swallowed the supply list. It holds 50+ pens and pencils plus scissors, sticky notes, and a calculator, with a wide opening so kids can actually see what's inside instead of digging blind. Sturdy canvas, real zippers, lots of colors. One of the most popular pencil cases on Amazon, for under ten dollars. Typical price: $9.99 Get it on Amazon →
