Product Information

This set of 11 PowerPoint Presentations (130 slides, excluding Title Pages) covers the following place value and approximations based topics:

• 01 Place Value – Integers (10 sides): Reviews place value columns and how to read and write whole numbers.

• 02 Place Value – Decimals (10 slides): Reviews place value columns and how to read and write decimal numbers.

• 03 Order and Compare Numbers (10 slides): Explains techniques for putting numbers (integers and decimals) into (ascending and descending) order, and how to use the inequality symbols when comparing two numbers.

• 04 Multiply and Divide by Powers of Ten (16 slides): Explains how to multiply or divide whole numbers and decimals by 10, 100, 1000, etc.

• 05 Standard (Index) Form (17 slides): Explains why standard (index) form is used, how to read and write values in standard form, and how calculators are used with this format.

• 06 Approximations – Rounding (18 slides): Explains how to approximate by rounding to the nearest 10, 100, 1000, etc.

• 07 Approximations – Decimal Places (8 slides): Explains how to approximate to a fixed number of decimal places.

• 08 Approximations – Significant Figures (8 slides): Explains how to approximate to a fixed number of significant figures.

• 09 Estimating / Checking Answers (11 slides): Explains how to use approximations to estimate or check answers.

• 10 Error Intervals (13 slides): Explains how to find the error intervals of numbers which have been approximated or truncated.

• 11 Error Bounds (9 slides): Explains how to find the minimum and maximum possible values of answers to questions involving approximated or truncated values.

Note:

• Work on multiplying and dividing by powers of ten as well as standard form is also included in the ‘Calculations‘ Pack.
