Luckily it is recently possible to remove the navibar.
1. In the edit mode of your blog, click the Layout menu on the left
2. Click Edit, and then click Off to turn off the navibar.
For elementary school I tend to encourage the use of blogging platforms specifically designed for education with younger students. Kidblog and Edublogs are two such options. Because of its simple design and more extensive free features, I prefer Kidblog, but both are worth consideration. The comparison chart below may help you choose for yourself. Both offer more extensive features (such as the abililty to login with a GAFE account or integrate with Google Drive) available through upgraded paid subscriptions.
