Around and Around We Go!
I love a good challenge and this week I gave my 2nd graders a new Dash challenge called Around and Around We Go!
I placed an x inside our tape squares and a rectangle in the middle. Their first task was to code Dash around the square and avoid the green rectangle in one button press or event.
I also created two student handouts. I wanted to make sure all group members would have a job to focus on during the task. We worked in groups of 3-4 students.
The first handout was used for recording the original code the groups created. I also asked them to briefly write about what happened when running the code.
The second handout was placed in a dry erase sleeve and used to guess and check their code as they worked.
The guess and check strategy was another important part of this lesson. I stressed to the kids that programmers write small parts of their code and then test them often. The kids did a great job with this!
Cheers could be heard around the room as groups completed a challenge.
Once they coded Dash around the square, I would give them another challenge.
Several groups made it through 3 of the challenges in 1 50 minute class period.
I loved how this activity turned out. It was open enough that groups could have creativity, yet challenging enough they really had to problem solve.
