These addition of decimals problems are intended to be follow-up practice after a lesson. Each group of problems adds a new layer of complexity (see list below for how each problem set is differentiated).

The red border represents the addition operation in Montessori math lessons and materials.

The following items are included in this material:
1. Addition of decimals problem tickets
- Problems #1-12: adding decimal fractions and decimal fractions
- Problems #13-24: adding more than two decimal fractions
- Problems #25-36: adding whole numbers and decimal fractions

2. Answer Key

3. Recording Sheet (The square in top right of each box is to record the problem number.)

Instructions
Print, cut and laminate. Alternatively, the whole sheets can be laminated without being cut to be used as a set of problems, rather than as individual tickets. The answer key is designed to be left as one whole sheet.

After giving a lesson, chosen tickets are handed by the teacher to students as follow-up practice. The students complete the work on their own, record on the recording sheet or in a math journal, then check their work using the answer key. Each problem ticket has a number on it that corresponds with the answer key.

Another way to use the tickets is to cut them up and have them in a basket for use as a math activity or center. The students can choose which tickets they complete based on the choices provided in the basket. After recording, students can check their work with the answer key.
