Whole and Part Workshop

It all started with the ubiquitous “is this right?” from many different students.  With that we began a series of mini-classes to teach children how to check their subtraction answers by using addition.  We also decided to use this opportunity to try and help children understand the relationship between the “whole and the parts”.  We Read More >>

Cooking with Kathy

A favorite Investigations activity for our students is to cook. Besides honing their cooking skills and working together, students connect their math and science knowledge to real life experiences. But everyone agrees that eating the results is the best part. After picking apples at Beak and Skiff Orchard in the fall, we had lots of Read More >>

Fractions with Kathy

Children in Kathy’s fraction class began by reviewing what a fraction is and what its parts represent. We developed our understanding of fractions and equivalent fractions using various tools, such as pattern blocks, fraction bars, pictures, number lines, and brownies. We practiced comparing, ordering, adding, and subtracting fractions. Our growing understanding of fractional relationships is Read More >>

Math Table

Our oldest two students have been participating in a math table all year where we work on math topics that include adding, subtracting, multiplying and dividing decimals, fractions and multi-digit numbers.  We’ve also worked on deductive thinking and story problems.

Fractions

Children in Rebecca’s fraction class started with a quick review of what a fraction is, the parts of a fraction and how to add and subtract fractions with like denominators.  We then moved on to equalizing fractions, reducing fractions and what a factor and multiple are.  Using our knowledge of equivalence, factors and multiples we have delved Read More >>

Coins Coupons and Combinations

Students in grade 1 and 2, explored the number system using Terc’s Investigations: Coins, Coupons and Combinations. First they worked with combinations of 10, making their own Book of 10, which listed all the possible combinations of 10. To further practice this skill they played games such as Turn Over 10 and Tens Go Fish. Read More >>

Data and Graphing

This fall the younger group of students in 2nd and 3rd  grades began a data class with Johnna our student teacher. Throughout this class the students demonstrated the ability to collect numerical data, represent class data in a variety of ways and develop language used to interpret data. Johnna modeled each step before the students Read More >>

Math Problem Solving

We value giving children the opportunity to problem solve and think critically.  A group of 2ndgraders met once a week to tackle problems such as: “How many feet would there be in our room if all the people living in your houses came to our class at the same time.” Or “If I found 50 Read More >>

Decimals

Students in grades 5 and 6 were part of a Decimal class based on the teaching of Marilyn Burns. To ensure students understood the relationship between decimals and fractions students used tens blocks to represent wholes, tenths, hundredths and finally thousandths. Playing games such as Sum and Difference, Decimal Wipe Out, Smaller to Larger,  helped Read More >>

Equalizing

Beginning in the Fall, a group of eight kindergarten, first and second graders took part in a math class focusing on Equalizing. Using a variety of manipulatives they investigated how to make different lengths and weights equal. They decided to add on or take away from two different lengths of string or chain links to Read More >>
