**Thursday, April 22 ^{nd} is Earth Day - We have 15 interesting activities that support recycling, conserving resources, noticing climate change and protecting our planet.**

**The shape of Louisiana** - At what rate is the state loosing land and wetland? Why is this happening? Will Louisiana ever just disappear? 5.MD, 6.RP.A, 6.GA, 7.RP.A, HSF.IF, HSA.CED, HSM

**Weather extremes** - Use the **open number line** and our lists of temperature extremes to make **signed number operations** and **absolute value** sensible. Students compare record high and low temps (integers) and use absolute value in order to always find the positive difference. Subtraction of negatives becomes obvious in this lesson.6.NS.5, 6.NS.6, 6.NS.7, 7.NS.1, 7.SP.3, 7.SP.5

**Which car should I buy? Electric or Hybrid** - Students create equations for finding the break-even points of these vehicles by mileage and years of ownership. They then work with systems of equations to find the number of years or number of miles where the cost of these cars are the same.6.SP, 6.RP, 7.RP, 7.SP, 8.SP, 8.EE.C, HSA, HSS.B, HSN

**Have you seen more Monarch butterflies lately? **- Students read charts, do a little research, and make observations about the decline and resurgence of Monarchs. MP4, 3.MD, 6.RP.A, 7.RP.A, 7.EE, 8.EE, HSN
