Below is a list of resources I like and use. It is a hodgepodge of good stuff for teaching math with video and images.

Estimation180
Estimation180 is great for warm ups but even better for getting students to practice predicting their answer which allows them to decide if their answer they calculate makes sense. 
Here is an example:
Estimate: Day 151
What is the value of pennies in the glass?
Questions we ask to get students thinking of reasonableness of their answers. Give an estimate that is too low. Give an estimate that is too high Give an estimate that is just right.

Act 1: The Water Balloon
Did you wonder when the balloon will blow? Give an answer too high, too low, just right.

Explain Everything as a delivery tool
We began many classes by grabbing an Explain Everything file from our Google Drive. Here is a picture of that file. 
Here are some more examples of using Explain everything as a “digital worksheet”
