Use numeral cards to generate a two digit number; spinner that holds 10, 20, 30, 40, 50 and another spinner to hold 10, 20, 30; another spinner that has Add/Join and Subtract/Separate/Difference.
To represent and justify with rekenreks, base ten blocks, unifix cubes, dimes, nickels, pennies, manipulative sized ten frame cards; record four related facts (and a number bond? Part-part-whole model?); color in on four ten by ten grids to compare the two partners’ results.
Students can also use 120 chart if they wish; if Expert, a 200 chart.- Directions Powerpoint and Handout in Drive
Use 12, 20, or 30 sided dice for students ready for the challenge. If a child rolls 2 ten sided dice they must decide with those digits which number they want to use first.
Generate your start number, your start value. What is your change? What is your result?
Have students build it on the Rekenrek, put it on an open number line, pennies, nickels, and dimes, 120 chart (prefab is concrete, and do not support our students owning it, if they have to fill it out it is more abstract), they need to represent their work with the highest students coloring in the grid.
They need to record a minimum of 8 number sentences for each turn:
54=10+44 10+44=54
54=44+10 44+10=54
44=54-10 54-10=44
10=54-44 54-44=10
Differentiation- students put their answer on the 120 chart. Students should do their math efficiently, not necessarily largest number first for addition.
