Expanded Form to 50 using Ten Frames 1-88
Since formal number names like "eleven," "twelve," and "twenty-six" do not emphasize tens and ones, use number nicknames that do. What's 11? It's 1 group of ten and 1 more, so its nickname is "1 ten 1." What's 26? It's 2 groups of ten and 6 more, so its nickname is "2 ten 6." Nicknames encourage Base 10 thinking.
