Objectives CCSS Math: Measurement & Data 3.MD.A.1: Tell and write time to the nearest minute and measure time intervals in minutes. Solve word problems involving addition and subtraction of time intervals in minutes, e.g., by representing the problem on a number line diagram. 4.MD.A.2: Use the four operations to solve word problems involving distances, intervals of time, liquid volumes, masses of objects, and money, including problems involving simple fractions or decimals, and problems that require expressing measurements given in a larger unit in terms of a smaller unit. Represent measurement quantities using diagrams such as number line diagrams that feature a measurement scale. Materials Needed Lakeshore Magnetic Teaching Clock Lakeshore Student Clocks - Set of 12 “Elapsed Time Word Problems” activity page Elapsed time worksheet Introduction Ask a student what time school starts. Write this time on the board under the heading “Start Time.” Then ask another student what time school ends. Write this time next to the start time under the heading “End Time.” Ask, “From the time school starts to the time it ends, how much time elapses, or passes?” (Invite students to respond and explain their reasoning and calculations.) Hold up the teaching clock and demonstrate how to set the clock at the start time and count the hours and minutes until the end time. (Hint: Move the hour hand first and have students count the hours aloud with you. Then move the minute hand and have them count the minutes.) Explain to students that you are going to teach them some strategies to help them calculate elapsed time.
Objectives CCSS Reading: Informational Text RI.3.7: Use information gained from illustrations (e.g., maps, photographs) and the words in a text to demonstrate understanding of the text (e.g., where, when, why, and how key events occur). RI.4.7: Interpret information presented visually, orally, or quantitatively (e.g., in charts, graphs, diagrams, time lines, animations, or interactive elements on Web pages) and explain how the information contributes to an understanding of the text in which it appears. Materials Needed “Three Cheers for Engineers!” reading passage Paper and pencils Introduction Provide students with a copy of the “Three Cheers for Engineers!” reading passage. Tell students, “Today we are going to read a passage titled, “Three Cheers for Engineers!” One practice of good readers is that they pay close attention to the text. As we read, I want you to think about the meaning of the text, the words that are used and other features on the page that are used to help interpret the text.”
Objectives Identifying and knowing the meaning of the most common prefixes and derivational suffixes Determining the meaning of the new word formed when a known affix is added to a known word Using common, grade-appropriate Greek and Latin affixes and roots as clues to the meaning of a word Materials Needed Prefix title cards Index cards Prefix die template Root-word die template Word meanings game mat Marker Tape or glue Scissors Paper Pocket chart or whiteboard Introduction Print and cut apart the prefix title cards. Hold up the cards one at a time for students to read. Tell students the meaning of each prefix: bi- = two im- = not un- = not mis- = wrong pre- = before re- = again Explain that knowing the meaning of the prefix can help them determine the meanings of words that have the prefix.
Objective CCSS Reading: Informational Text RI.3.3: Describe the relationship between a series of historical events, scientific ideas or concepts, or steps in technical procedures in a text, using language that pertains to time, sequence, and cause/effect. Materials Needed “The Earthquake that Changed Earth” nonfiction reading selection “The Earthquake that Changed Earth” graphic organizer and sample graphic organizer Cause & Effect Flip Book template Scissors Pencils or markers A copy of any other nonfiction text
