This cluster extends place value ideas that students explored in Grade 4 (100,000 to hundredths) to larger and smaller numbers (1,000,000 to thousandths). Students use various tools (ex. Calculator, zoomable number lines, meter sticks, place value blocks) to notice patterns when a number is continually multiplied or divided by ten to discover that a digit in one place is ten times as much as the digit to the right and ten times less than the digit to the left. Students compare decimals to thousandths using length and area models using >, =, and < symbols to record the results of comparisons. Students collect data using metric measurement that yields change over time and use it to make and interpret line graphs. Students continue to apply place value concepts to solve metric conversion problems using a conversion table. (See About this Cluster and the Unpacking Document below for more details on this cluster.)
