In this lesson, students will find patterns when counting by related numbers and explain the relationship of multiplication and division. This may be remixed to add additional supports to meet the needs of all learners.
Building on students' intuitive understandings of patterns and number relationships, teachers can further the development of number concepts and logical reasoning as described in the Number and Operations and Reasoning and Proof Standards. In this two-part example from Illuminations, virtual hundred boards and calculators furnish a visual way of highlighting and displaying various patterns and relationships among numbers. Using calculators and hundred boards together, teachers can encourage students to communicate their thinking with others, as discussed in the Communication Standard. In this first part, Displaying Number Patterns, the same patterns are displayed on a calculator and on a hundred board simultaneously. In the second part, Patterns to 100 and Beyond, students examine number patterns, using a calculator to move beyond 100. e-Math Investigations are selected e-examples from the electronic version of the Principles and Standards of School Mathematics (PSSM). The e-examples are part of the electronic version of the PSSM document. Given their interactive nature and focused discussion tied to the PSSM document, the e-examples are natural companions to the i-Math investigations.
For this assessment task, students skip count by 1's,5's,10's, or 100's to fill in the missing numbers.
This assessment may be used for instructional or assessment purposes. A scoring rubric is included.

This lesson is from Tools 4 NC Teachers. This lesson focuses on repeated addition and identifying errors in skip counting. The activities provide opportunities for teachers to discuss the role of dealing with errors while establishing a classroom community of mathematicians.
This task is from Tools 4 NC Teachers. It is intended to be used in Clusters 1 or 4 of Grade 3.
In this lesson students explore arrays through the context of flats of flowers. Students determine the total number of flowers and write an equation using equal addends. Students calculate the total cost of flats of flowers within 99¢ and represent cost with variations of quarters, dimes, nickels, and pennies.
In this lesson students solve a problem where skip counting by 5s and 10s is required to solve a real world problem. Students have some previous practice with skip counting to numbers beyond 100.
