PRODUCT DESCRIPTION

Students play a game called, “Spinning Equations”. They spin a 2-digit number spinner and a 1-digit number spinner, record the two numbers on a recording sheet, and use those numbers to write an addition equation. They apply strategies related to this standard to ensure their equations are correct. Such strategies include using a set of ten frames to model the 2-digit number, and then adding 1 to 9 beans (based on the result of spinning the 1-digit number spinner) to that ten-frame model, making a ten if possible. The remaining beans are placed on a blank ten frame to represent the 1-digit number. Open number lines and a 1 – 120 number grid are other ways students can solve equations and relate a strategy to a written format. There are six different two-digit number spinners with a unique color/pattern background each matching a smaller, one-digit number spinner. Students can work independently, with a partner, or in a small group. A complete set of spinners and an open-ended recording sheet are included in black line format. Paper clips, paper fasteners, a set of ten frames, and 9 dry beans (or small counters) are needed for each student. Provide each student with a copy of the open number line and a 1-120 number grid for use as they play.

This resource addresses Common Core State Standard 1.NBT.4: Add within 100, including adding a two-digit number and a one-digit number, [and adding a two-digit number and a multiple of 10] using concrete models or drawings and strategies based on place value, properties of operations, and/or the relationship between addition and subtraction; relate the strategy to a written method and explain the reasoning used. Understand that in adding two-digit numbers, one adds tens and tens, ones and ones; and sometimes it is necessary to compose a ten.
