The Subtraction Finger Charts or Working Charts are used to practice and memorize subtraction combinations. This resource includes:
- Finger Chart 1/Control Chart 1 (full control chart)
- Finger Chart 2/Subtraction Chart 1 (full chart)
- Finger Chart 3/Subtraction Chart 2 (mute or blank chart)
- A set of differences for each of the subtraction problems to use on the charts
These awesome charts can be used in traditional educational settings without any additional materials to reinforce the memorization and practice of sequences in subtraction. Here you can print your own and go! Save yourself hours of work and lots of money.
This material is suitable for any child – whether in a traditional Montessori environment or not.

Determine the unknown whole number in a multiplication or division equation relating three whole numbers. For example, determine the unknown number that makes the equation true in each of the equations 8 × ? = 48, 5 = __ ÷ 3, 6 × 6 = ?.
Fluently add and subtract within 20 using mental strategies. By end of Grade 2, know from memory all sums of two one-digit numbers.
Understand the meaning of the equal sign, and determine if equations involving addition and subtraction are true or false. For example, which of the following equations are true and which are false? 6 = 6, 7 = 8 – 1, 5 + 2 = 2 + 5, 4 + 1 = 5 + 2.
Multiply one-digit whole numbers by multiples of 10 in the range 10–90 (e.g., 9 × 80, 5 × 60) using strategies based on place value and properties of operations.
