Montessori Decimal Addition Task Cards | Decimal Board Practice

Help children move from concrete decimal board work to confident written decimal addition with these printable Montessori Decimal Addition Task Cards.

Decimal addition can quickly become confusing when children are still strengthening place value. They may know how to add whole numbers, but once tenths and hundredths are introduced, small errors begin to appear: digits are misaligned, decimal points are ignored, or regrouping becomes overwhelming.

This resource gives Montessori teachers and homeschoolers structured, colour-coded follow-up practice that keeps decimal addition connected to the Montessori decimal board and the concrete-to-abstract sequence.

Instead of giving children another generic worksheet, these cards help students practise one equation at a time in a clear, purposeful, and independent way.

What’s Included

This 5-page printable resource includes:

• 32 decimal addition task cards
• 16 static decimal addition cards with no regrouping
• 16 dynamic decimal addition cards with regrouping/carrying
• Colour-coded design to support Montessori decimal board work
• Answer key for checking and independent correction

Students will need access to a Montessori decimal board or decimal-board-style material to get the most from this resource.

Why This Resource Works

A common Montessori maths challenge is finding enough meaningful follow-up work after the key lesson has been presented.

This resource solves that problem by giving children repeatable decimal addition practice that is simple to prepare, easy to store, and useful year after year.

It supports:

• Decimal place value
• Adding decimals accurately
• Aligning tenths and hundredths
• Static decimal addition
• Dynamic decimal addition with regrouping
• Moving from concrete material to written equations
• Independent Montessori shelf work
• Small group lessons
• Revision and intervention

The colour coding helps reduce common decimal mistakes, especially misaligned digits and place value confusion. Children can work through one card at a time, check their answers, and build confidence without being overwhelmed.

Best For

This resource is ideal for:

• Montessori upper elementary maths
• Ages 9–12
• Homeschool decimal lessons
• Decimal board follow-up work
• Independent maths shelf work
• Maths centres
• Small group support
• Students who need extra decimal place value practice
• Teachers wanting low-prep printable Montessori decimal materials

Suggested Use

Use these task cards after children have been introduced to decimal addition with the Montessori decimal board.

Students can build each problem with the material first, then record the written equation. Begin with the static addition cards before moving into dynamic addition with regrouping. The answer key allows children to check their own work and correct mistakes independently.

This resource also works well as review before subtraction of decimals, multiplying decimals, fraction-decimal connections, money work, and percentage lessons.

Created by Montessori Kiwi

Created by a Montessori-trained teacher and school leader, this resource is designed for real Montessori classrooms and homeschool settings where children need purposeful repetition without busywork.
