Given a certain amount of points, how many line segments can you connect between them? How many close geometric figures can you create? These are the types of questions learners are asked to solve in a assessment-based worksheet.

Engage young mathematicians in developing their basic arithmetic skills with these great hands-on activities. Using Unifix® cubes to model a variety of single digit addition and subtract problems, children build a basic...

Understanding the inverse relationship between addition and subtraction is essential for developing fluency in young mathematicians. Zoe and RJ explain how three numbers can form fact families that make two addition and two subtraction...

Deepen the number sense of your math class with a short presentation on writing equations. Using the relationship between numbers, young mathematicians learn how to determine the missing operator in an equation. A number of opportunities...

Third graders take a set of data and turn it into a pie graph with an independent worksheet. Containing 10 sets of data, the resource reinforced data analysis skills that pupils can use throughout a graphing unit. 

First graders solve the sums up to 10 using the mental math strategy of number bonding. Thirty different addition facts on the worksheet allow for plenty of practice.

Data analysts are guided through the arrangement of whole-number data onto a line plot by listening and viewing a high-quality, animated, and narrated set of slides. 

Hit unlike fractions out of the park in a comparing fractions color by number (symbol) worksheet. Young mathematicians place <, >, or = to make each comparing sentence true. Then, they use a key to color accordingly. When complete,...

Build on knowledge of fractions to build fractions. Pupils use interactives that require building fraction models for given fractions or mixed numbers and identifying fractions or mixed numbers for given models. A lab area lets users...

How many people and animals can cram into a single bed? Find out with this cross-curricular math and language arts lesson. Following along with a reading of the children's book The Napping House by Audrey Wood, young mathematicians...

Learning math is so much more fun when it involves playing games. Following the rules of the classic game Memory, young mathematicians flip over two cards at a time as they look for numbers whose sum or difference is equal to the value...

Finally, it all adds up. Learners complete a number puzzle in which they investigate the sums of the digits one through nine in a cross pattern. They then try to determine what totals are possible and which ones are...

Two triangles are displayed on a coordinate plane. Youngsters apply a reflection and a translation to demonstrate their congruence. This exercise makes a terrific tool for teaching these concepts, or a way to assess learning.

Challenge young mathematicians' ability to compose and decompose shapes with this fun geometry puzzle. The goal is simple, locate all of the rectangles shown in a picture of three overlapping rectangles. Perform this activity as a whole...

Turn your pupils into engineers who are able to use scientific principals to design a ship. This long-term project expects pupils to understand concepts of density, buoyancy, displacement, and metacenter, and apply them to constructing a...

It keeps going, and going, and going ... how does the Juno space probe have enough power to travel to Jupiter? Junior astronauts use a THNKR "Why with Nye!" video to discover solar-powered science with the one and only Bill Nye. Topics...

This instructional activity certainly will not be a drag! Little engineers design parachutes that make use of air resistance and, as a result, slow the descent of the payload as much as possible. It is an opportunity to teach about many...

Multiply by two, and then divide by two. This worksheet provided practice for beginning dividers. Note that the publisher assigns this to CCSS.Math.Content.3.OA.6, but you would need to do some explaining to actually get this and the...

This printable contains 12 basic equations to be solved. The first one is worked out as an example, and the answers for all can be found by clicking on a "Show Answers" box found on the website. The publisher has identified this as...

Single-step addition or subtraction operations are applied in order to solve these 12 simple equations. An answer key is available, not so much for you, but perhaps to be used by learners as a self-correction tool. Note that the...

Practice, practice, practice! There are 35 problems to solve on this handout, all of them involving the multiplication of mixed numbers. Although the publisher has tagged it as designed for several Common Core standards, there are no...

Thirty quick problems make this an ideal assessment when learners are working with two-digit multiplication. Note that this has been identified by the publisher as aligned to meet CCSS.Math.Content.4.NBT.5, it is rather simple and likely...

Here is a set of 24 pairs of numbers for which kids reduce the ratios to their simplest form. It is a simple and straightforward assignment, meant by the publisher to address CCSS.Math.Content.6.RP.3. Note, however, that it only requires...

For this assignment, math whizzes identify angles as either being obtuse, acute, right, or straight. Students identify six angles. The publisher states that this is designed with CCSS.Math.Content.MD.6 in mind, but it really does not ask...
