Material name: Addition Charts – Montessori Addition Charts
Area: Mathematics
Purpose & developmental benefits:
The Addition Charts help children practice and memorize basic addition facts through a clearly structured and orderly chart system. By filling in results or checking sums through visual, hands-on work, children gradually develop strong mental calculation skills and number fluency. This material represents an important transition from concrete manipulatives to abstract thinking and the internalization of addition tables.
Skills children develop:
-
Memorize addition combinations
-
Increase speed and accuracy in mental calculation
-
Understand the relationships between numbers in addition
-
Develop concentration, self-discipline, and orderly work habits
-
Prepare for the Subtraction Charts, multiplication, and advanced mathematics
Recommended age: 5–7 years old
Materials & components:
-
A set of Addition Charts (typically Charts 1–5 in the Montessori sequence)
-
Charts printed with addition grids
-
Marker strips, number tiles, or recording tools (depending on the set)

Use in the classroom / at home:
-
Children complete addition facts using the charts, filling in or checking results
-
Daily repetition to reinforce addition tables
-
Individual work that supports self-correction
-
A preparatory step before the Subtraction Charts and multiplication
