12. * How do pictures support the relational thinking? * What can the animals do to make the seesaw balance?

13. * Grade level groups * Use both T/F and open sentences * Use more complex relationships for older students but not tricky computations * Post the number sentences * Explain why you selected those sentences – What relationships do you want them to see? * Helpful website for grades 3-8 – http://www.sandi.net/site/Default.aspx?PageID=1286 http://www.sandi.net/site/Default.aspx?PageID=1286
