Unit 2: Place Value
Mini-Unit 4: Understanding Decimals & Place Value
Lesson 4.1: Reading & Writing Decimals
This teacher-led small-group activity includes a printable math mat (for modeling decimals using money, fractions, and base-10 blocks) and 12 editable task cards.
Students will:
• build and represent decimals to the hundredths place using number lines, models, and money
• connect fractions, decimals, and word form to build understanding of equivalence
• write decimals in expanded and word form to show place value relationships
• describe and compare how tenths and hundredths represent parts of a whole
• use visual models and classroom money to make real-world connections
