Marble Math is a game on www.abcya.com that allows students to practice addition with manipulatives. Students can use the tool to practice addition. The game tracks the students' progress and shows students which answers are correct and incorrect. Students can use virtual manipulatives to assist them in correctly adding a number sentence. As students progress to the next level the problems get more difficult.

Through the use of real time questioning, instant result aggregation and visualization, teachers can gauge the whole class’ current level of understanding. Socrative saves teachers time so the class can further collaborate, discuss, extend and grow as a community of learners.
