Montessori Decimal Fraction Multiplication Task Cards | Multiply Decimals by Whole Numbers

New Shopify Description

Help children move beyond “just follow the rule” and actually understand what is happening when decimals are multiplied.

This Montessori decimal multiplication resource is designed for use with the Montessori decimal board when students are being introduced to multiplying decimals. The questions are colour coded in the Montessori style and provide a clear bridge between concrete decimal board work and written decimal multiplication. The resource includes decimal multiplication by whole numbers, decimal multiplication by decimals, word problems, higher-order thinking questions and a colour-by-code review activity.

Multiplying decimals can be confusing when students are asked to work abstractly too soon. These task cards give children structured practice so they can see the place value changes, build accuracy and grow in confidence before moving into more independent written work.
