After we read the The Gold Rush from Harcourt, we read the relating segments in the Nevada Our Home text book. These cause and effect maps helped my kids immensely and made for a nice display in the hallways. The first file is a cause and effect map about the Gold Rush. You can fill this one out after reading the Harcourt story. The second file is about how the CA gold rush affected NV. We filled this out after reading pg. 95 and 112-117 in Nevada Our Home. The third file is a cause and effect chart about mining improvements. Fill out after reading pgs. 118-120 in the Nevada Our Home text. The fourth file is a simple 3 Facts I Learned assessment sheet.
