This 2-page 3rd grade science check covers animal classification in five items on a single page. Students circle the invertebrates among eight names, such as ant, worm, squid and bee, then write the group for a rabbit, a parrot, a catfish, an iguana, a toad and a dolphin. Two multiple choice questions ask about dry scaly skin and the trait only birds have. A short answer explains why a dolphin is a mammal. Page 2 is the answer key.
“Tell invertebrates from vertebrates.”
Question 1 asks students to circle the four invertebrates.
“Name the group of a familiar animal from its traits.”
Questions 2 and 3 cover six named animals and a trait description.
“Explain with two reasons why a dolphin is a mammal.”
Question 5 asks for at least two reasons.
A row of eight names: horse, ant, owl, worm, trout, squid, lizard and bee. Students circle the four animals with no backbone.
Six boxes lettered a to f and a word bank of five groups that can be used more than once.
One question on the group with dry scaly skin that lays eggs on land, and one on the trait that belongs only to birds.
Students give at least two reasons a dolphin is classified as a mammal rather than a fish, on three lines.
Checked answers for the choice questions and a sample answer for the dolphin, with any two mammal traits earning credit.
End of unit check
Give it after the animal groups unit. Most students finish in one sitting, and the answer page makes marking quick.
Mark question 5 together
Question 5 asks for two reasons. Read three sample answers aloud and have students decide which would earn full credit.
Talk through the trap
Question 4 asks what belongs only to birds, and wings or eggs look tempting. Discuss why bats and reptiles rule both out.
