In this Number Talk, Elysha Passeggi engages her 4th grade students in a discussion about whether or not the sum of two two-digit numbers can be 238.
Number talks were developed for classroom teachers to engage students in “mental math” through grappling with interesting mathematics problems.
In this Number Talk, Fran Dickinson engages his 5th and 6th grade students in divining the function from the input and output numbers.
In this Number Talk, Debbie Borda and Antoinette Villarin engage their 7th grade students in mentally calculating the savings received by a student who paid $54 for an item that was discounted 40%.
These tasks are grade-level formative performance assessment tasks with accompanying scoring rubrics and discussion of student work samples.
NCTM is committed to offering standards-based resources that improve the teaching and learning of mathematics for each and every student.
Not a fraction expert? It’s ok, neither are penguins. But you can practice with this fun craft activity.
In this activity, students will compare maps showing worldwide temperature, precipitation, biodiversity, and soil nutrition levels to predict where on our planet rainforests are located.
In this craft activity, students will recognize, name, and compare the fractions 1/2, 1/4, and 1/8 by constructing a penguin out of portions of paper circles.
In this lesson, students practice mathematics and computational thinking to create scale models of themselves, and then apply these skills to create models of other large organisms.
How much space is in space? Students build a simple model and practice fractions to see how much space exists between different objects in our solar system.
These resources are to assist Teachers as they plan for non-traditional instruction including synchronous and asynchronous teaching and learning.
