NAP Locked down browser vs Battle Crunch Maths

The NAP Locked down browser allows students to securely participate in NAPLAN and NAP Sample tests on the Online National Assessment Platform. The application regulates access to utilities and system functions, prevents application switching and unauthorised device resources being used during an assessment.

Battle Crunch Maths is a fast-paced "cognitive gym" designed to help primary-school students build unstoppable math calculation speed, accuracy and confidence. Built around the concept of maths as a sport, the app challenges students to complete a high-density 20×5 question matrix against a ticking clock, instantly identifying and strengthening their arithmetic bottlenecks. It features a focus-driven Solo Mode for breaking personal bests, alongside a competitive Battle Mode where kids can safely race against their mates. Battle Crunch Maths does not replace classroom learning. It accelerates it. By turning daily repetition into an engaging game, it automates basic number facts so children can save their mental energy for advanced problem solving and school exam success. WHAT'S IN THE GYM • A WHOLE MATRIX TO CRACK: twenty numbers, each transformed by five random operations (add, subtract, multiply, divide, squares, cubes and square roots). One hundred cells, every round brand new. • THREE DIFFICULTIES: Easy, Medium and Hard tune the number range and which operations appear. • MAKE IT YOURS: choose exactly which operations show up at each level, now including simple ½ and ¼ fractions. • WORKOUT PAD: scribble your working out on any cell. Your handwriting turns into your answer. • RESULTS & RANKS: accuracy, time, a correction sheet, and a rank ladder from Math Recruit to Quantum Overlord. • BATTLE A FRIEND: invite a friend to the same grid and race in real time. • CLASSROOM ROOM: run a live race for a whole class (25+ players) with a real-time leaderboard. • WEEKLY CHALLENGE: one shared grid for every player each week. The fastest time tops the board. FOR TEACHERS • A CLASS THAT LASTS: make a class once, and it keeps its roster all term. No re-inviting anyone before every lesson. • A SIX-DIGIT CODE: read it out, parents type it in. That's the whole setup. • PARENTS OPT THEIR CHILD IN: a child joins because their own parent said yes. You cannot add a child yourself, by design. • RUN A CLASS RACE: one tap starts a race for the whole roster. You host it, so you never appear on your students' leaderboard. • SEE WHERE THEY'RE STUCK: accuracy and the hardest facts per operation, per child, built from the races YOU ran for YOUR class and nothing else. Never a child's practice at home, another class, or their all-time record. • A PRACTICE PLAN: the weakest facts across the class, ready to drill, exportable as CSV. • ATTENDANCE: who took part, who left part-way, who never joined. REWARDS THAT KEEP KIDS COMING BACK • EARN COINS: every grid you finish pays out coins. The harder the grid, the bigger the reward. • REWARDS SHOP: spend coins on fun stickers, avatar rings, profile icons and themes. Buy once, own forever. • 19 BADGES TO COLLECT: milestones, perfect grids, speed records and add / subtract / multiply / divide mastery. • DAILY STREAK: play every day to grow your streak, bank streak-freezes for busy days, and unlock streak milestones. • BATTLE STICKERS: send a playful reaction to your opponent mid-race. • FAMILY PROFILES: up to three kid profiles on one account, each with its own stats, rewards and look. • THEMES & WALLPAPERS: sage, ocean, forest and custom backgrounds. • FACE ID: optional quick sign-in.
