Activities focused on estimating group totals and comparing different sets of equal groups.
Students apply their knowledge of place value and comparison to solve real-world problems involving money and shopping within 1,000.
Students use place value strategies to compare and order three-digit numbers and money amounts, identifying the greatest and least values in a set.
Students locate and compare three-digit numbers on a number line, using the visual representation to determine which numbers are greater or less.
Students investigate different ways to represent the same value using coins, bills, and base-ten blocks, focusing on equivalencies like 100 cents being equal to 1 dollar.
Students explore three-digit numbers using base-ten blocks, standard form, expanded form, and word form, and compare equivalent representations like 100 and 10 tens.
A series of lessons adapted from Grade 4 Multiplicative Comparison to Grade 2 Equal Groups, focusing on building foundations for multiplication through repeated addition, arrays, and skip-counting.
