الدليل
A studio for Ukrainian grades 1-2 (the NUS textbook «Explore the addition and subtraction tables of 2», «Explore the addition tables within 20»). In the table the top row is the first addend, the red sign shows which number is added, and the bottom row holds the sums.
Read the table. Look at how the first addend changes and how the sum changes: when the first addend goes up by 1, the sum goes up by 1 too. Then cover the results and try to say them.
At the end come the tables within 20: each frame holds sums with the same result, for example ٩ + ٢ = ٨ + ٣ = ٧ + ٤ = ٦ + ٥ = ١١. When one addend goes down by 1 the other goes up by 1 and the sum stays the same.
