Introduction The Bridges Grade Three Supplement is a collection of activities written to enable teachers in Virginia to fully address the Mathematics Standards of Learning established by the state in 2009. This material is published online as downloadable files on the Math Learning Center website. See www.gotomlc.org/va. The activities included here are designed to be used in place of selected sessions in Bridges Grade Three starting in Unit One. All of the activities are listed on pages 2–4 in the order in which they appear in the Supplement. They are listed in recommended teaching order on pages 5–8. On pages 9–24, you’ll also find a set of sheets designed to replace the Planning Guides found at the beginning of Units 1, 3, 4, 5, 6, and 7 in the Bridges Teacher’s Guides. These sheets show exactly how the Supplement activities fit into the flow of instruction. We suggest you insert these sheets into your Bridges guides so you can see at a glance when to teach the Supplement activities through the school year. The majority of activities and worksheets in this supplement come in sets of three or more, providing several in-depth experiences around a particular grade level expectation or cluster of expectations. Many of the activities will take an hour of instructional time, though some are shorter, requiring 30–45 minutes. Almost all of the activities are hands-on and require various math manipulatives and/or common classroom supplies. The blacklines needed to make any overheads, game materials, and/or student sheets are included after each activity. Some of the supplement sets in this collection include independent worksheets, designed to be completed by students in class or assigned as homework after related activities. See page 26 for a complete list of materials required to teach the activities in each Supplement set. Note Third grade standards not listed on pages 2–4 are adequately addressed in Bridges and/or Number Corner sessions. For a full correlation of Bridges Grade Three to the Virginia Mathematics Standards of Learning, see pages i–vii.
