Unit 6 : Whole-Number Operations and Number Stories

In Unit 6, children will take another look at the addition and subtraction diagrams that were introduced in Unit 4.

Children will also learn a procedure for subtraction called the trade-first method.  The trade-first method is similar to the traditional subtraction method.  However, all of the "regrouping" or "borrowing" is done before the problem is solved.

Later in the unit, children will strengthen their understanding of multiplication and division as they act out number stories using manipulatives and arrays; complete diagrams to show the relationship in multiplication problems; and then begin to record corresponding number models.

Unit 7 : Patterns and Rules

Unit 7 focuses on three themes: number patterns, computation,and the application of Mathematics through the use of data.  Children will continue to use the 100-grid as a means of reinforcing numeration skills.  Children will also explore the patterns of doubling and halving numbers, which will help them  prepare for multiplication and division.

Computational work will be extended to several 2 digit numbers and to the subtraction of 1 and 2 digit numbers from multiples of 10.

Children will also learn to find complements of 10 and collect and interpret real-life data about animals and themselves.

Unit 8 : Fractions

In Unit 8 children will review and extend concepts of fractions.  Specifically, they will recognize fractions as names for parts of a whole, or ONE.

Children will have opportunities to learn that, as with whole numbers, many different fractions can name the same quantity.  For example 2/4 and 6/12 are both names for 1/2.

Children will also explore relationships among fractions as they work with pattern-block shapes and Fraction Cards that show shaded regions.

Unit 9: Measurement

In Unit 9, children will explore measurements of various types.  Children will both estimate lengths of distances and actually measure lengths of distances by foot, yard, centimeter, decimeter, and meter.  We will discuss how measurements are approximations.  We will use terms such as; close to, between, and about when describing measurements.  For more accurate measurements, children will measure to the nearest half-inch and half-centimeter.

In addition to measures of length, children will have opportunities to explore the areas of shapes using square inches and square centimeters.  Learning about the size of units of capacity and weight, such as;  cups, liters, pounds, and kilograms will also be examined.

Unit 10: Decimals and Place Value

In this unit, children will review money concepts, such as names of coins and bills, money exchanges, and equivalent amounts.  They will pretend to pay for items and to make change.

The unit also focuses on extending work with fractions and money by using decimal notation.  Children will use calculators for money problems and estimation.

Later in this unit, we will work with place-value notation for 5-digit numbers.  Here, as previously, the focus remains on strategies that help children automatically think of any digit in a numeral in terms of its value as determined by its place.  For example, children will learn that in a number such as 2,642, the 6 stands for 600 and the 4 stands for 40.
