This is a great app for kindergarten to 2nd grade children. The purpose of this app is to practice their addition and subtraction skills. In this game, your child will help save the sheep from the hungry wolf. Each correct answer will lower the fences gate to help the sheep jump over it. Try to save as many as you can! This is the fun game to improve your child's Math addition and subtraction skills. **Plus a progress report and setup option for a parent or teacher to control the level of difficulty to match your childs level. Included in the setup options are a timed mode to challenge kids, and other options to customize the number of questions and number of tries.***In this new version, we also included the hint option to show how to add or subtract numbers and the options to use column or math mountain to reveal the answer.Features1. Addition PracticeKids will learn and practice adding numbers up to three digits long.2. Subtraction PracticeKids will learn and practice subtracting numbers up to three digits long.3. Challenge IThis level is a mix of addition and subtraction together that will challenge kids to solve all different kinds of math problems. This absolutely improves your childs addition and subtraction skills.4. Challenge IIThis level is a matching math game. Kids have to match the equations (with same or different operations) that produce the same result. For example, 2+3 will match with 1+4, or 9-5 matches with 2+2. 5. Setup options Provides options to customize the level of difficulty to match your child. For example, you can select a specific area that your child is having a hard time with, like subtracting numbers in the tens or adding numbers to twenty, so that he or she can practice it over and over. This is really helpful for improving your childs Math ability Also, there are more options to set up a timer and customize the number of questions and number of tries. **Addition Settings1. X+Y = ? (X,Y are defined from number ranges as 0-10, 11-20, 21-100, or 101-200)2. Add zero: X+0 = ?, X+? = X3. Next numbers: X+1 = ?4. Odd/Even numbers: X+2 = ?5. Add by 1-digit numbers: X+A=? (A: 0-9)6. Add by 2-digit numbers: X+A=? (A: 10-99)7. Add by 3-digit numbers: X+A=? (A: 100-200)8. Add ten: 10+A = ?9. Sum to 10: A+? = 10, A+B = 1010. Sum to 20: A+? = 20, A+B = 2011. Add multiples of 10 (i.e, 10+40 = ?, 50+30 = ?) 12. Add multiples of 100 (i.e, 300+100 = ?, 200+500 = ?)13. Add doubles: A+A = ? **Subtraction Settings1. X-Y = ? (X,Y are defined from number ranges as 0-10, 11-20, 21-100, or 101-200)2. Subtract zero: X-0 = ?, X-? = X3. Previous numbers: X-1 = ?4. Odd/Even numbers: X-2 = ?5. Subtract by 1-digit numbers: X-A=? (A: 0-9)6. Subtract by 2-digit numbers: X-A=? (A: 10-99)7. Subtract by 3-digit numbers: X-A=? (A: 100-200)8. Subtract all: X-X = 0, X-? = 09. Subtract from 10: 10-A = ?10. Subtract from 20: 20-A = ?11. Subtract multiples of 10 (I.e, 60-40 = ?, 50-10 = ?) 12. Subtract multiples of 100 (I.e, 800-400 = ?, 500-200 = ?)13. Subtract ten: A-10 = ?6. Progress Report Provides a progress report (as a daily report) for a parent to see how well the children can add or subtract numbers.**All words have been recorded by professional voice talent. *** If you have any questions or problems related to our app, please email us at firstname.lastname@example.org.
