This short video and interactive assessment activity is designed to teach third graders about finding the expression not matching a given number.

This short video and interactive assessment activity is designed to teach fourth graders about finding the expression not matching a given number.

This short video and interactive assessment activity is designed to teach fourth graders about finding the incorrect equations.

This activity can be used to help find the main idea or keyword from a passage of text. This activity is excellent to develop vocabulary and deepen understanding of the content being examined. 

This short video and interactive assessment activity is designed to teach fourth graders about finding the number from figure patterns.

This short video and interactive assessment activity is designed to teach fourth graders about finding the total time given a distance between two objects.

This task helps students solidify their understanding of linear functions and push them to be more fluent in their reasoning about slope and y-intercepts. This task has also produced a reasonable starting place for discussing point-slope form of a linear equation.

This task "Uses facts about supplementary, complementary, vertical, and adjacent angles in a multi-step problem to write and solve simple equations for an unknown angle in a figure (7.G.5)" except that it requires students to know, in addition, something about parallel lines, which students will not see until 8th grade.

This task asks students to solve addition and subtraction equations with different structures so that they are able to see the connections between addition and subtraction more easily.

This short video and interactive assessment activity is designed to teach fourth graders about determining rate.

Allow students to express their own style with the classics.
You can find the originals and view/discuss them and learn about the artist. Then students can create their own interpretation of the famous piece of art.

We touch things every day: a coffee cup, a car door, a computer keyboard. Each time we do, it is likely that we leave behind our unique signature—in our fingerprints.
No two people have exactly the same fingerprints. Even identical twins, with identical DNA, have different fingerprints. This uniqueness allows fingerprints to be used in all sorts of ways, including for background checks, biometric security, mass disaster identification, and of course, in criminal situations.

Fingerprint analysis has been used to identify suspects and solve crimes for more than 100 years, and it remains an extremely valuable tool for law enforcement. One of the most important uses for fingerprints is to help investigators link one crime scene to another involving the same person. Fingerprint identification also helps investigators to track a criminal’s record, their previous arrests and convictions, to aid in sentencing, probation, parole and pardoning decisions.

Each person in the world has a set of fingerprints unique to them! Even though every print is different, they can be categorized into one of three general types:
-loops (found in 65% of the population)
-whorls (found in 35% of the population)
-arches (found in 5% of the population)

Analyzing fingerprints can be a tricky business, especially without computers to help. After categorizing a print as a loop, whorl, or arch, look for these individual features:
-core: in a loop fingerprint, this is the center of the loop. 
-delta: in loop and whorl patterns, this is an area where ridges meet from three directions. (There is usually one delta on a loop and two or more on a whorl.
-ridge end: notice where individual ridges come to an end. 
-bifurcation: notice where a ridge divides into two ridges (like a fork in a road)
-island: notice any short ridges cut off from others. 
-crossover: notice where any ridges appear to cross over each other.

Try your hand at fingerprint analysis! Two different fingerprints have been found at a crime scene. Compare them to the fingerprints of the 4 suspects on this website.
