Understanding 3-digit numbers is a crucial step in a child’s mathematical development, and it’s essential to provide them with a solid foundation through engaging and age-appropriate activities. This year, we’re excited to help you teach them these fundamental concepts with brand-new interactive instructional materials.

Explore the World of Place Value and 3-digit Numbers

Unlock the world of 3-digit numbers with an engaging instructional slide deck focusing on a variety of number representations using three-digit numbers. This teaching slide deck introduces the place value system and the concepts of number forms, including:

• Standard form
• Expanded form
• Word Form
• Base Ten Form (MAB Models)

Over the course of 19 slides, your students will turn, talk, write, and share their knowledge of the base ten system and the many ways that 3-digit numbers can be written. We have included a variety of interactive options for your students to practise their mathematical skills and plenty of opportunities for you to check for understanding.
