Find your personal number using your birthday! It is the month + date + year & month × date × year.

In this lesson,
students examine and draw representations of cubes and then learn how to analyze
these representations using complex numbers. Students use what they know about
operations on complex numbers to see if a drawing is an accurate representation
of a cube. They also learn how to generate complex numbers that will produce
such representations.
Pre-K-2
This activity provides opportunities for creative problem solving while
encouraging young students to estimate length and angle measure. Using
the Turtle Pond Applet,
students enter a sequence of commands to help the turtle get to the
pond. Children can write their own solutions using LOGO commands and
input them into
the computer. The turtle will then move and leave a trail or path
according to the instructions given.

Los estudiantes son inspirados a descubrir todas las combinaciones posibles de trajes que consisten de pantalones cortos y camisas. Los estudiantes ejercitan actividades para resolver problemas (incluyendo eliminacion y coleccion de datos organizados) a hacer sus conclusiones.

Sea gulls and crows feed on various types of mollusks by
lifting them into the air and dropping them onto a rock to break open
their shells. Biologists have observed that northwestern crows
consistently drop a type of mollusk called a whelk from a mean height of
about 5 meters. The crows appear to be selective; they pick up only
large-sized whelks. They are also persistent. For instance, one crow was
observed to drop a single whelk 20 times. Scientists have suggested
that this behavior is an example of decision-making in optimal foraging.

Interactive computer-based tools provide students
with the opportunity to easily investigate the relationship between a set of
data points and a curve used to fit the data points. As students work with
bivariate data in grades 9-12, they will be able to investigate relationships
between the variables using linear, exponential, power, logarithmic, and other
functions for curve fitting. Using interactive tools like the
one below, students can investigate the properties of regression lines and
correlation.

Students learn how to play the Product Game. As they play the game, students develop understanding of factors, multiples, and the relationships between them. Winning strategies are discussed. The Product Game was adapted from
Prime Time: Factors and Multiples, part of the Connected Mathematics Project, and was written by G. Lappan, J. Fey, W Fitzgerald, S. Friel and E. Phillips (Dale Seymour Publications, 1996, pp.17-25.)
