Students who work on this task will benefit in seeing that given a quantity, there is often more than one way to represent it, which is a precursor to understanding the concept of equivalent expressions.
This task gives students another way to practice counting and gain fluency with connecting a written number with the act of counting. This task should be introduced by the teacher and would then be a good independent center.
The most engaging way to practice counting with students is to have them count meaningful things in their lives. Since five-year-olds are very focused on themselves this is easily done by allowing them to count themselves, their friends and objects within the classroom that relate to their daily lives.
This short video and interactive assessment activity is designed to teach first graders about counting rectangles, squares, and triangles in composite figures.
This short video and interactive assessment activity is designed to teach fourth graders about counting right angles in a turn.
This challenging problem and brainteaser gives first graders an opportunity to compose and decompose squares.
This is an instructional task related to deepening place-value concepts. The important piece of knowledge upon which students need to draw is that 10 tens is 1 hundred.
This short video and interactive assessment activity is designed to teach third graders about counting vertices and sides in various shapes.
This unit will focus on knowing number names, the count sequence, counting to tell the number of objects, and comparing numbers. Understanding Numbers and how they work is essential in order to build a mathematical foundation.
The objective of this lesson is to gain automaticity counting to 100 and to establish the importance of multiples of ten. The final goal of this lesson is for students to be able to count by tens and articulate the term for this.
This short video and interactive assessment activity is designed to teach fourth graders about counting the angles in a closed figure.
This short video and interactive assessment activity is designed to teach fifth graders about counting the number of perpendicular lines.
This Nrich activity, in line with the theme for this month, offers an 'action' to perform on a group of numbers which pupils can continue and explore. Or, you could think of the writing down of the 'description' of a sequence as an action performed on that sequence. It might particularly appeal to those pupils who enjoy number work but who are perhaps not used to succeeding in this area.
This task involves solving equations with rational coefficients, and requires students to use the distributive law ("combine like terms"). The equation also provides opportunities for students to observe structure in the equation to find a quicker solution, as in the second solution presented.
This task presents a real world application of finite geometric series. The context can lead into several interesting follow-up questions and projects. Many drugs only become effective after the amount in the body builds up to a certain level. This can be modeled very well with geometric series.
This is a mathematical number sense puzzle designed for partners to work through.
It’s easy to take today’s ubiquitous colored crayons for granted, but they were the result of one individual’s innovation. Biebow introduces Edwin Binney—a mustachioed man and head of a carbon black factory—who wished to make color-pigmented wax crayons that reflected the world outside. The resource includes a lesson plan/book card, a design challenge, and copy of a design thinking journal that provide guidance on using the book to inspire students' curiosity for design thinking. Maker Challenge: Think about the school/community/world in which you live and identify a problem that could be solved with a new invention.
A document is included in the resources folder that lists the complete standards-alignment for this book activity.
This short video and interactive assessment activity is designed to teach fourth graders about creating largest and smallest numbers given digits.
This video explains how to create bar graph from a table of data. The vertical axis is scaled by threes.
This video explains how to create a fraction model to model a fraction greater than 1/2 and less and 1.
