# Math Cabinet

$100.00

With over 3,000 math problems, this comprehensive cabinet covers all math concepts encountered by lower elementary students, offering a structured pathway towards mastery. Topics range from static addition to pre-algebra concepts and includes 240 word problems.

**Why start with premade sets?** Before encouraging independent problem-creation, the gold standard, curated problems offer several benefits. Beginner learners gain valuable support, instantly checking their answers and building confidence with instantly available solutions and you can be sure that the problem is solvable with the materials the child is using. The flexibility of these problem sets allows you to utilize many materials from the Montessori prepared environment, from hands-on manipulatives like Golden Beads or Racks and Tubes to fully abstract problem solving, catering to various learning styles and fostering deeper understanding.
