Math Unit 1: Measurement

Math Unit 1: Measurement

We started our Unit 1 in Math: Measurement

Memorization is NOT a goal in the case of vocabulary words and multiplication facts. We encourage you to discuss the ideas and concepts through hands-on activities and conversations (in the home language) about how we use math in our daily lives. 

We encourage to make connections with your home language to help understand the concept.

In this unit students will: 

• Tell and write time to the nearest minute and measure time intervals in minutes. 
• Solve elapsed time, including word problems, by using a number line diagram. 
• Reason about the units of mass and volume. 
• Understand that larger units can be subdivided into equivalent units (partition). 
• Understand that the same unit can be repeated to determine the measure (iteration). 
• Understand the relationship between the size of a unit and the number of units needed (compensatory principle). 

VOCABULARY:

Visual Mathematics Online Dictionary: This resource includes definitions, pictures, examples, and related words for mathematical vocabulary. 

Analog Clock: A clock that shows time by moving hands around a circle for hours, minutes, and sometimes seconds

Digital Clock: A clock that shows time to the minute using digits

Mass: A measure of how much matter is in an object.

Measure: Use of standard units to find out size or quantity in regard to length, height, area, mass, volume, time, perimeter

Time: Seconds, minutes, hours, days, months, years, and so on. Time is shown on a clock or calendar.

Volume: The amount of space occupied by an object

ACTIVITIES AT HOME:

- Make records of important times of the day (wake-up, dinner, going to school, getting home from school, etc.) and practice telling how long between activities.

- Fill a small box with blocks (e.g., sugar cubes) to determine its volume. Brainstorm multiple strategies to determine the volume.

ONLINE RESOURCES/ACTIVITIES:

Teaching Time: Telling time to the minute

Can You Fill It?: estimating volume

Clockworks: practicing telling time
