PowerPoint | 44 pages|Grades: 1 - 2

An engaging 44-slide interactive PowerPoint to use when learning about 2-digit place value.

Use this interactive PowerPoint presentation when learning about place value up to 100.

Use these place value warm-up questions when teaching students about:

• reading and writing numbers in word, standard, and expanded form
• determining the value of a digit within a number
• composing and decomposing numbers
• generating a number greater than or less than a given number
• putting numbers in order
• identifying missing numbers on a number line.

As a class, work your way through the 20 problems presented on the 44 slides.

Students choose the correct answer from an option of four. When they select the incorrect answer, the PowerPoint will ‘buzz’. When they select the correct answer, the PowerPoint will ‘chime’ and transition to the answer slide.

To activate the interactive functions on this PowerPoint, ensure that you have ‘enabled editing’ and are viewing the PowerPoint as a ‘Slide Show’.

Implement this interactive PowerPoint as a warm-up prior to lessons, or as a review at the end of the unit before the assessment.

Add new slides and create your own class questions and answers using the editable function on the PowerPoint.
