Strengthening Critical Areas: Using standard units of measure Unit of Study: Applying standard units of measure Global Concept Guide: 1 of 1

Content Development  The learning activities included in the lesson ideas were selected as culminating tasks for linear measurement.  The classroom teacher can determine if tasks combining multiple measurement standards, as provided, are most appropriate or if it would be more appropriate to select activities to re teach specific standards as determined by analyzing previous student assessments.  Specific tasks for a variety of measurement standards are on the reteach slide.

Day 1  Use the lesson idea“Footsteps on the Rug” to reinforce the concept, the smaller the unit, the more iterations needed to cover a given length. Will Tommy or Dad have more footsteps on the rug? How do you know? Student Response I know Dad’s foot is bigger so he will have fewer steps to cover the same length that Tommy walked. So Tommy will have more foot steps. Or The longer the unit the fewer I need.

Day 2  Previously taught skills of estimation before measuring, measuring with different tools and creating a line plot all come together in the task “Kangaroo Jumps”.  Teachers will need to make some instructional decisions about which parts of this task to utilize in order to finish in the given time.  Essential components of this task are estimation, measuring, and creating a line plot.

Day 3/4  In the task “Giant Measurements” students utilize a variety of tools to measure and build a “giant” from butcher paper.  When groups compare giants, students will determine how much longer one object is than another.

Enrich/Reteach/Intervention Reteach A common misconception students may still have about measurement relates to the ruler. Students often think the numbers on the ruler are counting the hash marks not the space between the marks. Teachers can provide students with a ruler with hash marks and no numbers. Ask students to measure something shorter than the ruler. Facilitate discussion about the number of spaces and relate that to a traditional ruler.
