Draw numbers as bars to learn part-whole and differences, and solve fun word problems to find the missing ?!
About this app
Master elementary addition, subtraction, and word problems with this interactive Bar Model tool. By visualizing numbers as proportional bars, learners can intuitively grasp part-whole relationships and mathematical differences. Adjust the values of two parts to watch the total dynamically scale, compare two bars side-by-side to find their difference, or test your skills in the challenge mode to find the missing number in randomly generated word problems.
