Build understanding of expanded form with these partitioning 3-digit numbers slides. Students learn to represent 3-digit numbers in expanded form, seeing how the same number can be shown in standard form, expanded form, number words and base ten blocks, then practise identifying the number represented by a given expanded form.
The intro slides model one number across all four representations side by side, helping students connect the expanded form back to the whole number before working independently.
What's included:
Introduction slides showing a worked example across standard form, expanded form, number words and base ten blocks
12 practice slides where students identify the 3-digit number represented by its expanded form
Hive members also have access to the Base Ten Blocks app, giving students another way to connect expanded form back to a concrete block representation.
