Students across the country will walk out of their classrooms for 17 minutes to commemorate the 17 victims who lost their lives in the February 14 shooting at Marjory Stoneman Douglas High School in Parkland, Florida.
The group said in a statement that they collected 7,000 pairs of shoes for the memorial to bring "the heartbreak of gun violence to Congress' doorstep".
The shoes will be donated when the monument is dismantled.
According to marchforourlives.com, which has a map of planned protests across the country, there are also events planned for Clearwater, Pinellas Park, Brandon and Plant City.
The massacre was the deadliest school shooting since 20 children and six adults were shot dead at Sandy Hook more than five years ago.
The Centers for Disease Control and Prevention reports almost 13 hundred U.S. Children under the age of 17 are killed by guns every year. The figure used by Avaaz would amount to approximately 6,825 children killed by guns in that time period.
Members of the AVAAZ group install 7000 shoes on the lawn in front of the U.S. Capitol in Washington, March 13, 2018.
Although there was no link to any figures or date, Avaaz said the study found that guns kill an average of "1,300 American kids a year".
The silent protest is meant to spur lawmakers to take action on gun reforms.
