Differentiated math worksheets for part-part-whole, number sense, and missing addend practice with numbers through 10.

Use these sheets in your differentiated math work stations for composing and decomposing numbers up to ten. The part-part-whole box is another take on number bonds. It's a great graphic organizer that will help students understand the composition of numbers.

Three levels of differentiation are included:

  • Below Level - Provides visual support (dots) and partially filled equation.
  • On Level - Provides visual support (dots), but equation is blank for student completion.
  • Advanced - Provides no visual support. Students use number sense to complete the missing part and equation.

You get unique practice pages for :

  • Parts of 5
  • Parts of 6
  • Parts of 7
  • Parts of 8
  • Parts of 9
  • Parts of 10
  • Mixed Practice Sets A through E

That's 11 different ways for your students to practice their part-part-whole number sense, and each is differentiated into the aforementioned levels.

Answer key is included. The clickable Table of Contents makes navigating the file easy for you!

to see state-specific standards (only available in the US).
Decompose numbers less than or equal to 10 into pairs in more than one way, e.g., by using objects or drawings, and record each decomposition by a drawing or equation (e.g., 5 = 2 + 3 and 5 = 4 + 1).
For any number from 1 to 9, find the number that makes 10 when added to the given number, e.g., by using objects or drawings, and record the answer with a drawing or equation.
Represent addition and subtraction with objects, fingers, mental images, drawings, sounds (e.g., claps), acting out situations, verbal explanations, expressions, or equations.
