Wrap-Up
BackgroundTwo teachers with the same problem
A = L ● W
P = 2L ● 2W
UNITS? Inches or square inches
3rd Grade &
Algebra Readiness
BackgroundTime and Creativity
No Time to Re-teach!No Time for favorite
activities!
BackgroundTeaching choices are often 25% - 40% off
standardOften add levels of difficulty that go beyond
standard.
Whole lessons and/or concepts are not grade level.**
** This does not mean kids can’t do the math or that it’s not grade level appropriate. It just might not be a priority.
Instead of extending “concept development” we extend
“difficulty”. (Ex. Equivalent Fractions)
Instead of backward planning from a good assessment we cover
the lessons.
Background
BackgroundGoals
Prioritize instruction (Focus on what’s most important).
Work to extend concept development on priorities.
Look for opportunities to pre-teach and embed concepts across the curriculum.•Where does my teaching fit in the
program?•What can I rely on from previous instruction?•What’s viewed most important by the next grade level?

• Estimates are more common than “exact answers”
• Estimates reveal understanding and/or gaps in conceptual understanding.
