• Algebra saves chickens
• How to touch Grass:
Locate an area of grass. The first step in touching grass is to find a place where grass is present. This can be a lawn in your backyard, a park, a sports field, or any other location where grass is growing. Make sure you have access to the area and that it is safe for you to be there.

Stand or kneel in a comfortable position. Once you have found an area of grass, stand or kneel in a comfortable position. If you are standing, make sure you have good balance and are able to maintain your balance while reaching out to touch the grass. If you are kneeling, place a cushion or towel under your knees for added comfort.

Extend your arm(s) in front of you, with your hand(s) open and fingers extended. This allows you to easily reach the grass and feel the texture and sensation of the blades.

Slowly lower your hand(s) towards the grass. Take your time and move slowly to ensure that you don't accidentally step on or damage any of the grass.

Allow your fingers to come into contact with the blades of grass. You may feel the softness and/or dampness of the grass depending on the environment. You may also feel the different temperatures of the grass if you are in a place with a different climate.

Gently move your fingers through the blades of grass, feeling the texture and sensation of the grass. Take note of the different feelings and textures you experience.

Repeat step 6 as desired, moving your fingers through different sections of the grass to experience the variety of textures and sensations.

When you have finished touching the grass, stand or rise back to your original position. Take a moment to appreciate the experience and the sensation of the grass on your fingers.

Note: If you are allergic or have any medical condition that may affect you to touch the grass, it is recommended to consult with your physician before attempting this activity.
• how is algebra creative?
• It does not say algebra is creative, it says there is creativity in algebra. There are a lot of number sense tricks based on algebra. For example, the difference of perfect squares (x-a)(x+a)=x^2-a^2. We can thus multiply 43*37 and get 40^2-3^3=1591. It makes the times table make more sense, if 5^2=25, then 6*4=25-1=24, 7*3=25-4=21, 8*2=25-9=16. 8^2=64, so 7*9=64-1=63. You can prove that 35^2=(30*40)+25=1225. The video talks about Algebra is not just Math, but has practical purposes in the real world that allows for all sorts of creativity.
• This is a fantastic addition to your program. Often times, we skip over the depth, beauty and complexity of the design of Algebra. I look forward to more of this because a lot of students want to know how this will help them in life and although I give them many reasons from daily life, more examples and explanation is most welcome!
• Sal looks different today...
• Hi Sal
• I'm so confused. None of the questions in each sections of the video was answered directly by the speakers. It's almost like there is zero connection
