# Graphing Stories Response

A. Choose TWO of the following graphs.  Create a story that describes each of the graphs (label A-F).  Make sure that you identify and describe the two variables (Distance from Home (y) and Time (x)).  Use appropriate math vocabulary.

B. Write a short description of how the two stories you wrote are similar/different based on the graphs you chose!

# Few Factors…Many Multiples

The fourth grade students have been exploring factors and multiples.  Their interest in factor trees and factor rainbows inspired some additional work on greatest common factors and least common multiples! Using their factor trees, the fourth graders have learned to find the prime factorization of a number which is helpful in determining the GCF and LCM of large numbers!

We have learned that the minds of are our classmates can be very helpful when solving a problem!

# Learning About Number Systems: Quipus

The first unit in third grade math Navigate will introduce students to a variety of number systems.  To start the year off, we learned about and created Quipus.  Quipus were used by the Incas to represent numbers at a time when a written number system did not exist.  A series of strings and knots allowed the trained Camayos to read numbers and stories using the Quipus.  This number system is similar to our own because it uses a base ten system.  Each student created their own quipu, which proved to be a lot more challenging than writing out the digits in our number system!  We used these quipus to answer the questions in the number stories that the students wrote to accompany their quipus.

# A Pumpkin Project

With Halloween quickly approaching, it seemed appropriate for the fifth graders to use their knowledge of variables to take a look at some pumpkins.  After identifying possible variables, they were ready to get messy while counting the ribs on the pumpkins, measuring circumference and diameter, and recording the number of seeds in each.  They were surprised by just how many seeds they had to count!

Their next step will be to identify the correlation between variables in order to draw conclusions and graph the results.  As a class we will work to determine the volume of the pumpkins and determine the true meaning of Pi!

# Problem Solving in 1st Grade

The first graders are becoming a great group of problem solvers!  They have learned to approach difficult math tasks by using the different problem solving strategies we have practiced in class!  The Navigate students have learned to draw pictures, use objects, make tables, and find patterns to take on new and challenging math tasks!

# Math Navigate World Records

The fifth grade Navigate students have been exploring variables.  Through the use of Guinness World Records, they have learned to identify, graph and describe the correlation between variables.  The fifth graders also attempted to take on a world record of their own by challenging Ashrita Furman’s “Record with a Peel!”

# Problem Solving in Second Grade

The Second Grade students have been exploring problem solving strategies.  Using the PLANE method, they have been taking on a variety of math tasks!
