Number talks are a great way to get your students involved in meaningful mathematical discussion! This poster shows the hand signals that are used as part of the number talks routine. It includes both an English and Spanish poster.
To decrease the amount of interruptions in your classroom, use a class signal for each need a child may have. Instead of a child raising their hand and disrupting the class, my students have shown me our class signals and with a simple head nod, their need is answered. I posted this little sign in the front of my classroom as a reminder for my students. I printed this sign on colorful and bright card stock paper and laminated it. The signals include: Bathroom Tissue Drink New pencil Question
Using these hand signals in class will help the flow of class continue and not get interrupted by someone having to raise their hand and ask to go to the restroom or sharpen a pencil. My field teacher uses these and it works wonders!
