In this lesson, students build a two-digit number using Arrow Cards, describe the value of a two-digit number based on the digits in the tens and ones places. Students can organize the cards horizontally or vertically to represent numbers in expanded form (35 = 30 + 5). They can overlap cards and line up the arrows to form multi-digit numbers.
