Reflection: Greater Than- Exploring What It Means To Have More - Section 2: Presentation of Lesson


In this lesson, it is very important to see if students understand the difference between equal and unequal groups.  I found that my students did very well with the activities on the carpet and finding the group of concrete objects that had more, but when they moved to their paper, many students were drawing extra lines when matching the objects in an attempt to give each object a partner.  They were then stating that the groups were equal.  I addressed this issue to the whole class, and I pulled the students who did this back to my table to practice during centers.  When completing the small group activity, I used the wiki sticks and color tiles.  This activity helps students practice using lines to connect the objects, but by using wiki sticks instead of a pencil line, you can limit the number of lines that the students can draw.  The difference that I see in how my students perform on activities with concrete objects and pencil and paper tasks is why I find it so important to do a combination of activities during each lesson.
