While reading over a Scope and Sequence for first grade math I came upon the following, “Estimate quantities to 100 using an anchor”
What does that mean? I’m visualizing depictions of various quantities of anchors–the student glances at them and estimates how many:
My quirky mental image aside, I’m quite sure they are using the word “anchor” in a more figurative sense… but I’m honestly not grasping exactly what is intended. (And I thought our PrairieFrog Scope and Sequence for first grade was odd. )
Someone fill me in?
