With this card game, students practice constructing two-digit numbers using tens and ones. The game includes a work mat, tens & ones for counting, directions, a recording page, and at least 3 number cards representing each tens group from 10 to 99.
This game can be used as 2 separate games:
1) For the Pre-K & K game, make 2 copies of each of the first 2 sets of cards (only the teens),
but include only 3 "Lose 2" cards in the game. 2) For a more difficult version, simply make one copy of each page of cards, including numbers
from each tens group. You can add or remove cards in order to make the game more appropriate for the skill levels of your students.
This game addresses the following Common Core
Math Standards for kindergarten and first grade:
K.CC.4. Understand the relationship between numbers and quantities; connect counting to cardinality.
K.CC.5. Count to answer how many? questions about as many as 20 things arranged in a line, a rectangular array, or a circle, or as many as
10 things in a scattered configuration; given a number from 1 to 20, count out that many objects.
K.NBT.1. Compose and decompose numbers from 11 to 19 into ten ones and some further ones, e.g., by using objects or drawings, and record each
composition or decomposition by a drawing or equation (such as 18 = 10 + 8); understand that these numbers are composed of ten ones and one, two,three, four, five, six, seven, eight, or nine ones.
1.NBT.2. Understand that the two digits of a two-digit number represent amounts of tens and ones. Understand the following as special cases: 10 can be thought of as a bundle of ten ones called a ten. The numbers from 11 to 19 are composed of a ten and one, two, three, four, five, six, seven, eight, or nine ones. The numbers 10, 20, 30, 40, 50, 60, 70, 80, 90
refer to one, two, three, four, five, six, seven, eight, or nine tens (and 0 ones).
