This program teaches students to make words from letters and then to make sentences from words. The student first sees the letters of a word in their correct order. The student then moves the letters into spaces provided to form the word. The student next sees the letters “scrambled,” i.e. in random disorder. The student then puts the letters in order in the spaces provided to form the word. After that, the student sees scrambled letters with distracters, and must choose correct letter in the correct order to make the word. It is basically an grammar dictionary that will check your work for you! And you get the convenience of being able to carry it with you all the time. Don't turn in that paper to your instructor until you've run grammar checker and fixed any little errors. Use it on your emails, so that your boss is impressed with your writing ability.

Every parent knows the struggle: getting kids to do chores, stay on track, and understand that good things come to those who wait. Kidderboard makes it simple. Kidderboard is the family app that turns everyday activities into rewarding achievements. As a guardian, you assign activities like homework, tidying up, or practising an instrument. When your child completes them, they earn Kidderbux — points that celebrate their effort and teach them the value of consistency. HOW IT WORKS Set up your family board in minutes. Add your children, choose from ready-made activities or create your own, and assign them with a tap. Your child sees their tasks, marks them done, and waits for your approval. Approved activities instantly earn Kidderbux. THE VAULT: TEACHING PATIENCE THAT PAYS OFF The Vault is where the magic happens. Children can save their Kidderbux in the Vault and watch them grow over time — just like a real savings account. It’s a gentle, visual way to teach delayed gratification without any real money involved. GOALS THAT MOTIVATE Set activity-based goals like “Complete 10 activities this month” or “Make your bed 7 times.” You can even create guardian-verified goals for bigger milestones like “Learn to ride a bike.” Every completed goal earns bonus Kidderbux. CORRECTIONS WITHOUT CONFLICT When behaviour needs addressing, apply a correction. Children see a friendly explanation of what needs improving and the Kidderbux adjustment — no arguments, no shaming. You can undo corrections too, because everyone deserves a second chance. DESIGNED WITH FAMILIES IN MIND • Child-safe: no free text, no peer comparison, no public leaderboards • Multi-child support: manage your whole family from one account • Secondary guardians: invite a co-parent or carer to help manage • Badges and milestones: celebrate streaks and achievements • Full transparency: every Kidderbux change is logged and explained Whether your child is 6 or 16, Kidderboard grows with them. Start your free trial today and bring a little more structure — and a lot more fun — to family life. For terms of use, please see https://www.kidderboard.com/terms
