Place Value Presents: 1.M. NBT2.-Understand that the two digits of a two-digit number represent amounts of tens and ones.
Let it Snow- A Game of Time: 1.M. MD.3.-Tell and write time in hours and half-hours using analog and digital clocks.
Elfie Learns to Measure: 1.M. MD.2.-Express the length of an object as a whole number of length units, by laying multiple copies of a shorter object (the length unit) end to end;
understand that the length measurement of an object is the number of same-size length units that span it with no gaps or overlaps. Limit to
contexts where the object being measured is spanned by a whole number of length units with no gaps or overlaps.
Stocking Subtraction Match: 1.M.OA.6.-Add and subtract within 20, demonstrating fluency for addition and subtraction within 10.
Fill Up Santa’s Bag: 1.M.OA.1-Use addition and subtraction within 20 to solve word problems involving situations of adding to, taking from, putting together, taking apart, and comparing, with unknowns in all positions, e.g., by using objects, drawings, and equations with a symbol for the unknown number to represent the problem.
Santa’s on Top of the Roof: 1. M.NBT.3-Compare two two-digit numbers based on meanings of the tens and ones digits, recording the results of comparisons with the symbols >, =, and <.
Fa-la-lah Fact Famlies: 1.M.OA.3- Apply properties of operations as strategies to add and subtract.3 Examples: If 8 + 3 = 11 is known, then 3 + 8 = 11 is also known. (Commutative property of addition.) To add 2 + 6 + 4, the second two numbers can be added to make a ten, so 2 + 6 + 4 = 2 + 10 = 12. (Associative property of addition.)
