When my DD was in first, we had a bad period with math. I pushed for extension (not normally provided) and they had someone do small group pull out with logic and reasoning puzzles and it helped a lot. She wanted it every day. At home, we did games like Yahtzee and apps like The Room, and had to rebuild her confidence. It was so hard. She hated the repetition, and the questioning, that feeling like she was being tested on numeracy she knew. It created doubt. It's still frustrating at times.
