4th Grade Math 11.5, Word Problem Solving, Unknown Angle Measures

We can use what we know about angles, and the strategy draw a diagram, to solve angle measurement problems. We can use the relationship between the known and unknown angle measures to draw a bar model. We can use the bar model to write an equation. We review the steps to solving word problems. We solve four word problems involving unknown angle measures. We see how extending lines or rays, then using what we know about straight angles and right angles, will help us solve a problem. We see how an angle will not change if we extend its rays. We review acute, right, obtuse, and straight angle measures. 4th Grade Math 1.7, Subtract Whole Numbers with Regrouping, Renaming https://youtu.be/xWN5YCt9cNc 4th Grade Math 1.8, Word Problem Solving, Comparison Problems with Addition & Subtraction https://youtu.be/-ao7M5md2pY 4th Grade Math 3.7, Word Problem Solving, Multiply 2-digit Numbers https://youtu.be/ad-uaeDf_x8 4th Grade Math 4.11, Divide 1-Digit Numbers, Check With Multiplication https://youtu.be/WpzaDnN3dwI 4th Grade Math 4.12, Word Problem Solving, Multi-Step Division Problems https://youtu.be/Kq4Gyoh7lGg 4th Grade Math 11.1, Angles & Fractional Parts of a Circle, or Clock https://youtu.be/0lx41EZEVcM 4th Grade Math 11.2, Degrees & Fractional Parts of a Circle https://youtu.be/JB3aPkek9Vw 4th Grade Math 11.3, Measure Angles, Draw Angles https://youtu.be/NFPm3TaYwhY 4th Grade Math 11.4, Join & Separate Angles https://youtu.be/UQm2bstbb7g 4th Grade Math Playlist https://www.youtube.com/playlist?list=PLKi4WTp6PRGX7RhcxctRibNb7V091JZfn I'm using the Houghton Mifflin Go Math! 2015 copyright textbook for this playlist.
