A number talk is a short (10-15 minute), ongoing daily routine that provides students with meaningful practice with computation. Tools should be used during second grade number talks to provide a context for reasoning with numbers. Some examples of tools appropriate for second grade are rekenreks, ten-frames, double ten-frames, open number lines, and hundred charts.
Differences Between Shingles and Hives. Shingles is caused by the varicella zoster virus, same as chicken pox. Hives are a skin reaction to many different things, including pets, soaps, foods, and medications. 2. Hives cause red and itchy welts to form on parts of the skin but do not cause blisters.
Shingles is a painful viral infection of the nerve roots. The virus moves along the nerve fibres and affects cells of the skin, resulting in a skin rash. It is caused by the herpes varicella-zoster virus, the same virus that's behind chickenpox. The virus is never fully cleared from the body and shingles occurs when the virus reactivates.
