"In order for students to tackle the multi-step word problems they'll be asked to solve as early as elementary school, they need to have mastered their addition, subtraction and multiplication facts. By answering 4 + 12, 15 - 5, 9 x 7 and 18 / 3 quickly and accurately, students can focus on reading word problems to figure out what the question is asking them to do. There are tons of fun apps that help children build their math fluency through games and flashcards. Check out some of these fantastic math apps."
