" If you would like to share a fun math game with your child, be sure to check out Astro Math: Grades K 3." (theiPhoneMom.com) Astro Math: Grades K-3 is a reliable follow-up resource for common core standardized lessons. The app includes math facts covering kindergarten through 3rd grade school curriculum. By protecting each planet individually a student goes through levels practicing grade-level appropriate math skills (counting, addition, subtraction, multiplication, division). The student collects coins upon successfully completed missions and is given a chance to buy with the same coins an array of defense systems in the Armory. Next to math skills, this app also teaches students facts about planets of our Solar System. Astro Math: Grades K 3 was designed relying on common core math standards in the U.S.A. The following skills are expected from students to achieve towards the end of each grade level: -Kindergarten students should know whole numbers, count sequence by ones and by tens, compare numbers; they should understand addition and subtraction. -1st grade students should know whole numbers to 100, count sequence by twos and fives; they should develop strategies for adding and subtracting whole numbers based on their prior work with small numbers; they should use addition and subtraction within 20 to solve word problems.-2nd grade students should use their understanding of addition to develop fluency with addition and subtraction within 100; they should understand place value, as well as multiplication process/division. -3rd grade students should represent and solve problems involving multiplication and division; they should multiply and divide within 100.
