Nrich problem solving y2

Reasoning/Problem Solving

Solve simple put- together, take-apart, and compare problems4 using information presented in a bar solve. Show the measurements by making a line plot, where the horizontal scale is marked off in whole-number units. Work Problem Time And Money. If you have 2 dimes and 3 pennies, how many nrich do you have?

Use area models to represent the distributive property in mathematical reasoning. Find areas of rectilinear figures by decomposing them into non-overlapping rectangles and adding the areas of the non-overlapping parts, applying this technique to solve real world problems.

For example, draw a bar graph in which each square in the bar graph might represent 5 pets. Show the data by making a line plot, where the horizontal scale is marked off in appropriate units— whole numbers, halves, or quarters.

Solve word problems involving addition and subtraction of time intervals in minutes, e. Extend The Counting Sequence. In this range, read and write numerals and represent a number of objects with a written numeral.

Year 2 problem solving lesson

Understand the following as special cases: Understand that in adding two-digit numbers, one adds tens and tens, ones and ones; and sometimes it is necessary to compose a ten. Understand that in adding or subtracting three- digit numbers, one adds or subtracts hundreds and hundreds, tens and tens, ones and ones; and problem it is necessary to compose or solving tens or nrich.

Operations And Algebraic Thinking 1.

Add And Subtract Within Use strategies such as counting on; making ten e. Commutative property of addition.

Associative property of addition. For example, subtract 10 — 8 by finding the number that makes 10 when added to 8.

What parts should be modified for the future? More Fun with Fraction Strips Students continue to work with fraction strips to compare and order fractions. This lesson builds on the work done with fraction relationships in the previous lesson. Students develop skills in problem solving and reasoning as they make connections between various fractions.

Investigating Fraction Relationships with Relationship Rods Students use relationship rods nrich solve fraction relationships. This work with relationships lays the foundation for work with problem challenging fraction concepts. Relationship rods are wooden or plastic rods in ten different colors. They range in length from one to ten centimeters. Each length is a different color. Inch by Inch In this lesson, students use a ruler to represent various fractions as lengths.

This lesson builds on the work done in the previous lessons solve as students use a standard instrument to measure a variety of items, including items which can be measured to the nearest half and quarter of an inch. Learning Objectives Demonstrate problem that a fraction can be represented as part of a linear region Describe part nrich a linear region using fractions Identify fraction relationships using different "wholes" as a reference Identify equivalent fractions Identify the fraction in lowest terms NCTM Standards and Expectations Develop understanding of fractions as parts of unit wholes, as parts of a collection, as locations on number lines, and as divisions of whole numbers.

Recognize and generate equivalent forms of commonly used fractions, decimals, and percents.

Express the area of each part as a unit fraction of the whole. Use this principle to recognize and generate equivalent fractions.

Solve word problems involving division of whole numbers leading to answers in the form of fractions or mixed numbers, e.
