For Teachers · Practical Ideas for Real Classrooms

Teaching Resources for Real Classrooms

Free and low-cost tools, classroom-tested strategies, and ready-to-use ideas for math, science, collaboration, and classroom routines. Start with what helps your students think—and keep the planning manageable.

01 / USE IT TOMORROW

Ready-to-use tools for your classroom

Two short routines you can copy into a slide, form, or lesson plan. Start with the one that solves a problem in your next class.

5 minutes · any subject

A three-question exit check

Use this at the end of a lesson to decide what to teach next. Students can answer on paper or in a Google Form.

Show what you know: Solve or explain one example from today’s lesson.
Explain your thinking: What step, observation, or piece of evidence supports your answer?
Tell me what you need: What is one question you still have?

Teacher move: Sort responses into ready to move on, needs a quick check-in, and needs another example. Start tomorrow with the most common question.

8 minutes · discussion

A discussion script

Give every student a chance to form an idea before the confident voices take over.

“Take one quiet minute to form your own idea. You do not need a finished answer. Tell your partner what you tried and what you are unsure about. Your partner’s job is to ask a question before offering advice. Then choose one idea your group can show on the board.”

Find the full Classroom Playbook ↗ for timing, materials, and more prompts. Try 30-Second Partner Teach, Think, Talk, Rotate, Record, or One-Minute Exit Check.

02 / PLAN ONCE, REUSE OFTEN

Save planning time with repeatable systems

Keep the lesson purposes consistent from week to week and change the content. Copy the planning template and feedback starters into the tools you already use.

Weekly planning template

A simple rhythm for the week

Launch on Monday, build understanding on Tuesday, collaborate on Wednesday, apply on Thursday, and demonstrate learning on Friday. An exit check on any day can guide the next lesson.

This week’s big question: __________ What students should explain or do by Friday: __________ Monday’s launch: __________ One collaborative task: __________ One independent task: __________ Friday’s evidence of learning: __________ Students I need to check in with next week: __________

Copyable feedback starters

Give a specific next step

“Your model shows [specific strength]. Explain why [step or relationship] works.”
“You identified [observation]. What evidence connects it to your conclusion?”
“Your answer addresses part of the question. Check [condition] and revise.”
“Try representing the information in a table, sketch, or equation. Which makes the pattern easiest to see?”

Add a detail from the student’s actual work before sending feedback. These are reusable teacher systems, not automatic grading tools.

03 / KEEP IT CLEAR

Routines for a more independent classroom

Teach a routine once, model it, then use the same steps with new content. Predictable directions help students begin and work together with less prompting.

Starting class

What students do when they enter

Enter and go to your assigned seat.
Read the prompt on the board.
Begin independently.
Mark a question if you get stuck so you have something specific to ask.

Practice the steps explicitly, then keep them visible as the class begins.

Group problem solving

What students do with a group

“First, think on your own. Then share a starting idea. Make your group’s thinking visible. Before you call the work finished, check every condition in the problem and make sure another student could follow your explanation.”

Choose a Classroom Playbook routine ↗ by purpose: Start class, Discussion, Science inquiry, or Check understanding. Each activity gives a teacher guide, student prompt, example, and what to look for.

04 / INVESTIGATE

Make hands-on learning easier to plan

Choose a question students can answer with evidence. This short planner works for manipulatives, observations, design challenges, and simulations.

Copyable teacher planner

The 20-minute investigation planner

Question students will investigate: __________ What students will change or compare: __________ What they will observe or measure: __________ Materials and safety check: __________ How they will record evidence: __________ What they will explain at the end: __________

Decide what evidence will count before you set out materials. Close by asking, “What did you observe, and how does it support your explanation?”

Try it with what you have

Three easy starting points

Dice: Generate results, represent the data, and explain a pattern.
Dominoes: Model ratios or fractions and compare two strategies.
Leaves or photographs: Record specific observations before suggesting explanations.

The Classroom Playbook ↗ has full routines for Variable Sort, Observation Stations, and Dice: Fraction, Decimal, Percent. For a digital investigation, find a simulation in the Technology & Learning Resources collection ↗. Give students a prediction, two observations, and one evidence-based claim.

Review any outside website, activity, and safety requirements for your own students before assigning it.

05 / MAKE THINKING VISIBLE

Give students more ways to show what they know

Offer different formats while holding onto the same goal: students state an idea, show evidence, and explain how the evidence supports it.

Choose a format

What to ask students to include

Student product	Evidence of learning
Visual model	Labels, relationships, and a short explanation
One-minute video	A claim, an example or evidence, and a conclusion
Written response	A claim, supporting evidence, and reasoning
Worked solution	A model or strategy, calculations, and a check
Peer explanation	A clear explanation followed by one partner question

Copyable project prompt

One question, several ways to respond

“Choose one way to explain [concept]. Your work must show what you think, include evidence or an example, and explain how that evidence supports your idea. Before submitting, ask someone: ‘What part is clear, and what question do you still have?’ Revise one part based on their response.”

Quick review

Four questions to check the work

Can I identify the student’s idea?
Can I see the evidence?
Can I follow the explanation?
Did the student revise or check the work?

MORE LEARNING, LESS SPENDING

Low-cost materials that do more than one job

A few reusable supplies can support dozens of number-sense routines, investigations, reviews, and formative assessments.

Dice

Use for integer operations, probability, coordinate pairs, ratios, fractions, and random data generation.

Playing Cards

Build and compare fractions, generate expressions, order rational numbers, or create probability experiments.

Dominoes

Model ratios, fractions, operations, equivalent expressions, and quick number-talk prompts.

Sticky Notes

Collect exit tickets, sort vocabulary, gather evidence, graph class data, or run a gallery walk.

Index Cards

Create retrieval practice, task cards, lab roles, student groups, matching activities, and quick checks.

Everyday Objects

Use containers, paper clips, cups, string, or classroom items for models, measurements, and design challenges.

Teacher tip: A low-cost material becomes valuable when students must make a decision with it—not simply move it around.

CLASSROOM-TESTED

Strategies that cost nothing

Strong routines give students a clear way to begin, discuss, organize, and explain their thinking.

Discussion Routine

Notice, Think, Wonder

Display an image, graph, model, specimen, or short demonstration. Students record what they notice, what they think may be happening, and what they wonder.

Collaborative Learning

Think, Talk, Rotate, Record

Students think independently, share strategies, rotate responsibility, and record a model or explanation another group can follow.

Academic Writing

Claim, Evidence, Reasoning

Students state a conclusion, identify observations or calculations that support it, and explain how the evidence connects to the claim.

Productive Struggle

Ask Before You Tell

Try: What do you know? What representation could help? Which condition have you not used? How could you verify your answer?
