    Love that you are mixing-up addition and subtraction which is called “interleaving” under the 6 cognitive learning strategies. This is particularly effective in mathematics and has shown effective results in long-term memory. So thanks. Now to a problem situation:

    A teacher bought 20 pencils for her class. One week later she only had 14 pencils left. How many pencils did she give to her students?

    Result known and start known change unknown.

    for some reason image will not post.
