Математические пазлы#1 к 14 февраля (натуральные числа)

On the eve of St. Valentina proposes math puzzles for a mathematical warm-up for schoolchildren:

🔺15 pairs of cards for addition of three-digit natural numbers
🔺15 pairs of cards for subtracting two- and three-digit natural numbers
🔺15 pairs of cards for multiplying three-digit natural numbers by one- and two-digit
🔺15 pairs of cards for dividing three-digit natural numbers into one- and two-digit ones.

All math puzzles presented in two versions: colored hearts and black and white.

Total in file:
🔺60 pairs of colored hearts (120 halves)
🔺60 pairs of black and white hearts (120 halves)
🔺Keys for a quick check

Tasks and results are on different halves of the hearts and placed on the sheet in different places.

Math puzzles can be used in the following ways:
👉 You can print colored hearts or b/w on colored paper, laminate (or just stick sticky tape), cut it out and ask the students to match the corresponding halves of the hearts.
👉 You can print one or more black and white pages for each student and ask them to connect the halves of hearts with an arithmetic operation and its result with a line.
👉 You can think of a lot of options for use.
