Giants of the Past

Check out some ancient—and enormous—animals

Meet the Titanoboa (ty-TAN-oh- BOH-uh). As long as a school bus, this monster snake could swallow an entire crocodile! It lived 58 million years ago. Scientists found its remains in 2004 in the South American nation of Colombia. So far, it’s the largest snake ever found. A life-size model is at the National Museum of Natural History in Washington, D.C.

Titanoboa is long gone. But some of its distant family members live on. Researchers think the Titanoboa is related to much smaller snakes that live in the Americas today, like the boa constrictor and the anaconda.

Many smaller animals that exist today are related to giants of the past. Check out this skills sheet to learn more.

Multiplying 2-Digit by 1-Digit Numbers

Here’s one way to multiply a 2-digit number by a 1-digit number:
→ Stack the equation.
→ Break apart the 2-digit number into tens and ones.
→ Multiply each place by the 1-digit number.
→ The two results are called partial products. Add them to get the product of the original numbers.
Example: 43 x 5 = ?
→ 43 = 40 + 3 (4 tens and 3 ones)

43 ← 40 + 3
x 5
200 ← 5 x 40
+ 15 ← 5 x 3
215

The Lamb and the Butterfly

by Arnold Sundgaard and Eric Carle

Eric Carle and Arnold Sundgaard's classic tale is now available in a redesigned edition.

One day, a Lamb and a Butterfly meet in a meadow. The Lamb, cautious and dependent upon her mother, is curious about the Butterfly's independent way of life. Meanwhile, the free-spirited Butterfly doesn't understand the sense of security that the Lamb needs from her mother.

When an unexpected storm injures the Butterfly, the Lamb and her mother care for her, nursing her back to health. Once she's better, the Butterfly must resume her journey, flying away from the meadow. As the Lamb and the Butterfly try to understand each other's perspective, we learn an important lesson about recognizing and respecting differences between ourselves and others.
