This set of making 10 and problem solving online activities focuses on the following foundational skills:

• Missing Addends
• Solving for 10
• Numbers to 100 on a Hundreds Chart
• Using Data in Categories
• Number Patterns

This set focuses on solving problems in multiple ways or getting more than one answer or solution.

Games linked from this page practice Common Core Standards:

• K.MD.3 – Classify objects into given categories; count the numbers of objects in each category and sort the categories by count.
• K.OA.3 – 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).
• K.OA.4 – 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.
• K.CC.5 – Count to answer “how many?” questions about as many as 20 things arranged in a line, a rectangular array, or a circle, or as many as 10 things in a scattered configuration; given a number from 1-20, count out that many objects.
• K.CC.6 – Identify whether the number of objects in one group is greater than, less than, or equal to the number of objects in another group, e.g., by using matching and counting strategies (include groups with up to 10 objects).
