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 the reactivation of a viral infection in the nerves to the skin that causes pain, burning, or a tingling sensation, along with an itch and blisters in the skin supplied by the affected nerve. It is caused by the varicella zoster virus[1] , or VZVâthe same virus that causes chickenpox.ZV belongs to a group of viruses called herpesviruses. This group includes the herpes simplex virus (HSV) that causes cold sores, fever blisters, and genital herpes. Like VZV, HSV can hide in the nervous system after an initial infection and then travel down nerve cell fibers to cause a renewed infection.
