## Reflection: Connection to Prior Knowledge Skip Counting with 5s, 10s and 100s - Section 2: Teaching the Lesson and Independent Practice

This lesson was designed to take prior rote counting by 5s and 10s and to extend it to counting beyond 100, as 100 is the expected limit for grade 1 in the Common Core, and also to extend to counting by 100s.

Students all demonstrated proficiency in counting by 5s,  and 10s within 100. Once we moved over 100, some of the students faltered.

To help with extending the learning from their prior knowledge, I wrote the counts above 100 on the board. We looked at patterns. Students began to notice how the pattern below 100 repeated itself above 100 with a 1 in the hundred's place being the only change.

As we worked with the number line and recording counts in smaller groups, students again looked for and identified patterns.

Student discovery is a stronger way to help students learn a concept than to just tell them what the concept is and hope they remember it.
