Routines library

Ten routines that carry most of the evidence.

I do, we do, you do	New material	"Watch me. Now with me. Now you, while I check."	2
Split-page worked example	New problem type	Solved problem left; twin problem right	3
Hinge question	Before moving on	Four choices; letter cards up; decide to move on or reteach	4
Brain dump	Any review	"Everything you remember. Three minutes. Go."	6
Mixed review set	Homework, warm-ups	Old and new problem types, no headings	8
Whole-class feedback	Day after a task	Show the two most common errors; class fixes them	5

One table per unit; build once, reuse every year.

Must-know item	Taught (date)	Review +1 day	+1 week	+3 weeks	+6 weeks	On final

When the adopted materials are weak in places, fix the gaps inside them rather than replacing them:

Add a daily review of earlier lessons at the start (principle 6).
Put a worked example in front of every new problem type (principle 3).
Reorder practice sets so they mix in earlier units (principle 8).
Add a check for every student before independent work (principle 4).
Remove guessing prompts in early reading, such as "look at the picture" (principle 9).
Connect reading passages to a topic you can teach for several weeks (principle 10).

None of these require new materials or permission to throw out the curriculum.
