Build Events

They seem like a lot of fun, BUT they take a lot of Time:

Please only choose no more than 1.

VERRRRYYYY FEW 5th graders can complete

If you built for us last year, you can talk to the coaches about more.

34 of 34

5th Graders (1-2 events) - at least 1 constant

6th Graders (1-3 events) - at least 1 constant

7th Graders (2-3 events) - maybe a constant

8th Graders (3-5 events) - maybe a constant
