This year for angles,we learned how to measure with a protractor.A protractor goes up to 180 degrees. If it is 90 degrees that is a right angle.If it is above 90 degrees it is a obtuce angle.And if it is below 90 degrees that is a acute angle.Durin 4th grade in multipacation I learned 2 diget x 2 diget.You use a certain chart hat you can do it on.It is a tic-tac-toe chart.You write a x sign at the top left corner and break the numbers up under and beside.My favorite thing this year is transformations.Translation,reflection,and rotation.Translation are the igsact same as the other.Reflection is like looking in a mirror.And rotation is changing the direction of the object.We learned what volume is. It is not the one on your t.v.its in 3-D shapes.Leighthxwidthxhighth.Near the end of the year we learned square routes.Lets do 5×5=25 the square route of 25 is 5.
