El bullicio de la multitud está disminuyendo y el zoológico se queda en silencio por la noche. El oso polar toma la pelota y la rebota sobre la cancha; el juego nocturno comienza. Una rana se une al juego para jugar uno a uno y luego, un pingüino entra caminando como un pato para unirse al equipo. Cuenta cómo va creciendo el juego conforme se va su mando cada nuevo animal y el campo de jugadores llega a diez. Tres cebras sirven participan como árbitros y llevan el cronómetro, porque este juego debe terminar antes que la cuidadora del zoológico haga sus rondas.
Tape measures are among the most commonly used tools in any handyman's or handywoman's arsenal. This book will help students develop word recognition and reading skills while discovering what these incredible tools can do and how they do it. They will also find out how tape measures can be used to tackle specialized projects. Additional text features and search tools, including a glossary and an index, help students locate important information and learn new words.
From the five lines on a music staff to the seven colors of the rainbow, all the way up to the famous 100th day of school, Number 1 Teacher: A School Counting Book takes a by-the-numbers approach to helping young readers understand and identify many of the concepts and lessons they'll learn in elementary school. There are 3 forms of matter we learn in science class-- One is liquid; two is solid; and the third is gas. Geography, music, and how to tell time are just a few of the many topics featured.
This Level 2 guided reader teaches how to interpret and create tally charts. Students will develop word recognition and reading skills while learning about counting, skip-counting by 5s, and representing numbers using tally charts.
El recuento de la clásica historia con un giro matemático. Lucas, la liebre, siempre estaba presumiendo acerca de lo rápido que él era. Un día, reta a la tortuga Teodora a una carrera de una milla cuesta arriba a la colina. Lucas salta hacia adelante en el primer octavo de la milla. Mientras Teodora se acerca, él lo vuelve a hacer otra vez. Las medidas de fracciones y distancia marcan su progreso mientras Lucas y Teodora corren a la línea de meta
A retelling of the classic story with a math twist. Henry Hare was always bragging about how fast he was. One day he challenges Tessie Tortoise to a mile-long race up the hill. Henry leaps ahead for the first eighth of a mile. As Tessie approaches, he bounds ahead again. Fractions and distance measurements mark their progress as Tessie and Henry race to the finish line.
Cuando Elías y su padre visitan tan inusual zoológico, ellos cuentan a las criaturas en cada una de las exhibiciones. Elías ve un cocodrilo, después un bisonte y luego, dos camellos. De repente, surge un patrón numérico y Elías piensa que él puede predecir cuántos animales habrá en la siguiente exhibición. Explora el zoológico con Elías mientras él avanza hacía adelante para probar su hipótesis
When Eli and his father visit an unusual zoo, they count the creatures in each exhibit. Eli sees one alligator, then one bison, and next two camels. Soon a number pattern emerges and Eli thinks he can predict how many animals will be in the next exhibit. Explore the zoo with Eli as he runs ahead to test his hypothesis.
