which circles are divided into fourths select all that apply well to be divided into fourths that means we have to be divided into four equal sections because a fourth is going to be one of the four equal sections so all of these are divided into four sections but not all of them are divided into four equal sections for example this one it's divided into four sections but this section right over here is bigger than this section right over here and it's bigger than this section over here so this isn't four equal sections but these top three it looks like four equal sections it looks like each of these four sections are equal each of these four sections are equal each of these four sections are equal so all of these all of these up here are divided into fourths and this one isn't so I won't click on that one let's keep going this is fun which squares are divided into fourths select all that apply well same idea we have to be divided into four equal sections so all of these are divided into four sections one two three four one two three four but not all of them are divided into four equal sections for example this one right over here this section is this little triangle is much smaller than this section so these aren't equal sections but for the other three they are four equal sections this is each of these triangles that this square is divided into these are all equal they all have the same area so that's four equal sections each of these smaller squares they all have the same area so that's four equal sections and then each of these four rectangles are all the same size they all have the same area so that's four equal sections let's keep going I'm having a lot of fun all right which circles are divided into thirds well if you're to divide two thirds you have to be divided into three equal sections so this one is divided into four equal sections so this is divided into fourths so it's not thirds this is divided into three sections but they're not equal this section right over here is smaller than this section right over here this one is divided into three sections and they're all equal this section has the same area as this section has the same area as that section so I'll check that one this one is three but they're not equal just like this one this one this section is much smaller than this section so this is the only one that is really divided into thirds which circles are divided into thirds same idea this is divided into fourths these aren't equal sections not equal sections this one is divided into thirds let's do one more which rectangles are divided into fourths remember for its it needs to be four equal sections this looks like four equal sections this is two equal sections this is divided into halves not fourths this is four equal sections this is divided into six equal sections so it's equal sections but not four it's six equal sections so this right here is divided into sixths so our two rectangles that are divided into fourths are this one and that one four equal sections
